A., and Adoui, L.

Abstract

Interaction between slow multiply charged ions and small to medium-size neutral water clusters is investigated. Strong projectile charge dependence is found for all of the fragmentation patterns. A variation of the projectile charge dramatically changes the proportion of multi-electron removal, the fragment kinetic energies as well as the mean size of the emitted fragments. First results for highly charged ion - water cluster ion collisions will also be presented.

Abstract

We report on measurements of the ionization and fragmentation of polycyclic aromatic hydrocarbon (PAH) targets in Xe(20+) + C(16)H(10) and Xe(20+) + [C(16)H(10)](k) collisions and compare results for the two C(16)H(10) isomers: pyrene and fluoranthene. For both types of targets, i.e., for single PAH molecules isolated in vacuum or for isomerically pure clusters of one of the molecules, the resulting fragment spectra are surprisingly similar. However, we do observe weak but significant isomer effects. Although these are manifested in very different ways for the monomer and cluster targets, they both have at their roots small differences (<2.5 eV) between the total binding energies of neutral, and singly and multiply charged pyrene and fluoranthene monomers. The results will be discussed in view of the density functional theory calculations of ionization and dissociation energies for fluoranthene and pyrene. A simple classical over-the-barrier model is used to estimate cross sections for single-and multiple-electron transfer between PAHs and ions. Calculated single and multiple ionization energies, and the corresponding model PAH ionization cross sections, are given., authorCount :17

Abstract

We report on an experimental study of the ionization and fragmentation of clusters of k polycyclic aromatic hydrocarbon (PAH) molecules using anthracene, C14H10, or coronene, C24H12. These PAH clusters are moderately charged and strongly heated in small impact parameter collisions with 22.5-keV He2+ ions, after which they mostly decay in long monomer evaporation sequences with singly charged and comparatively cold monomers as dominating end products. We describe a simple cluster evaporation model and estimate the number of PAH molecules in the clusters that have to be hit by He2+ projectiles for such complete cluster evaporations to occur. Highly charged and initially cold clusters are efficiently formed in collisions with 360-keV Xe20+ ions, leading to cluster Coulomb explosions and several hot charged fragments, which again predominantly yield singly charged, but much hotter, monomer ions than the He2+ collisions. We present a simple formula, based on density-functional-theory calculations, for the ionization energy sequences as functions of coronene cluster size, rationalized in terms of the classic electrostatic expression for the ionization of a charged conducting object. Our analysis indicates that multiple electron removal by highly charged ions from a cluster of PAH molecules rapidly may become more important than single ionization as the cluster size k increases and that this is the main reason for the unexpectedly strong heating in these types of collisions.

108. Multiple ionization and fragmentation of isolated pyrene and coronene molecules in collision with ions

B., Rosén, Stefan, Schmidt, Henning T., Zettergren, Henning, Manil, B., Adoui, L., Cederquist, Henrik, and Huber, B. A.

Abstract

The interaction of multiply charged ions (He2+, O3+, and Xe20+) with gas-phase pericondensed polycyclic aromatic hydrocarbon (PAH) molecules of coronene (C24H12) and pyrene (C16H10) is studied for low-velocity collisions (v <= 0.6 a.u.). The mass spectrometric analysis shows that singly and up to quadruply charged intact molecules are important reaction products. The relative experimental yields are compared with the results of a simple classical over-the-barrier model. For higher molecular charge states, the experimental yields decrease much more strongly than the model predictions due to the instabilities of the multiply charged PAH molecules. Even-odd oscillations with the number of carbon atoms, n, in the intensity distributions of the CnHx+ fragments indicate a linear chain structure of the fragments similar to those observed for ion-C60 collisions. The latter oscillations are known to be due to dissociation energy differences between even-and odd-n Cn-chain molecules. For PAH molecules, the average numbers of H atoms attached to the CnHx chains are larger for even-n reflecting acetylenic bond systems.

Abstract

We report the first experimental study of ions interacting with clusters of polycyclic aromatic hydrocarbon (PAH) molecules. Collisions between 11.25 keV He-3(+) or 360 keV Xe-129(20+) and weakly bound clusters of one of the smallest PAH molecules, anthracene, show that C14H10 clusters have much higher tendencies to fragment in ion collisions than other weakly bound clusters. The ionization is dominated by peripheral collisions in which the clusters, very surprisingly, are more strongly heated by Xe20+ collisions than by He+ collisions. The appearance size is k = 15 for [C14H10](k)(2+)., authorCount :16

111. Production and Transport of Projectile Excited States in Solids

Author

Abstract

Two different types of descriptions can be used to calculate the slowing down of a projectile through materials. For both approaches, improvements towards fully ab initio calculations are attempted by several groups while, in the past, the prediction of stopping power of heavy ions had to rely on the use of "free parameters" like the effective nuclear charge of the projectile. The first description assumes that ion-solid interaction is the result of a series of binary collisions with the target electrons. In this collisional picture, the evolution of charge state distributions of the projectile at the exit of solid targets, involving core state populations, can be successfully predicted in many cases (like for the ETACHA code). In the other one (the dielectric theory), the target electrons are considered to respond collectively to the passage of the projectile. The polarization of the medium can be described as a wake of electronic density fluctuation trailing the ion. The gradient of the wake potential defines an electric field responsible for the stopping power. This electric field also acts directly on the excited levels of the projectile and will induce, among other effects, binding energy shifts as well as Stark mixing of substates. Until recently, only "quasi-free" target electrons were considered in this approach. Up to now, it exists in fact very few experimental results that can be used to decide which of these pictures is the most appropriate and to define eventually their validity limits. In particular, tests on the predictions of the wake model concerning the spatial extension of the electronic density fluctuations are needed. Atomic physics experiments can be used to shed some light on ion-matter interaction. Looking at one partner of the collision, namely the excited state populations of the projectile, the response of the material may be probed.

112. Single and Multiple Excitation Processes in Heavy Ion-Atom Collisions at Intermediate Velocity

Author

Abstract

The knowledge of the processes involved in swift heavy ion-atom collisions can be considered as the first step in the understanding of ion-matter interactions. This picture corresponds to a given description of the projectile stopping power. In this respect, the intermediate velocity regime (vp ≡ ve , where vp is the projectile velocity and ve the mean orbital velocity of the active electron) is of particular interest : the ion stopping power is nearly maximum and for applied purposes, the understanding of mechanisms accounting for radiation damage in materials is important. However, in this velocity range, experimental determination of monoelectronic process cross sections is not so simple since the excitation, ionization and capture channels are of the same order of magnitude and may influence each other strongly. On the other hand, the role of target electrons as active partners, via capture channel coupling and direct target electron-projectile electron interaction, is not well known. So far, these effects are not taken into account even by the most sophisticated theories. Furthermore, multiple processes, involving more than one electron of the projectile and of the target as well, are actually under study and ask for much debated questions.

Abstract

The energy distributions of H+ fragments produced in N7+ + H2 collisions at projectile energies ranging from 1.4 keV down to 32 eV have been investigated experimentally as a function of the detection angle. At 1.4 keV, two groups of peaks are clearly visible, especially at forward angles. The structure centered at energies lower than ∼ 20 eV, corresponds to a double capture at relatively large impact parameters, whereas the highly energetic protons result from capture events at very small impact parameters. The results from a quasiclassical calculation method show a good agreement with our experimental data for the fragment energy distributions. At the lowest projectile energy, the fragment energy is found to be independent on the detection angle. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
