The article describes a new detector, a volume filled with hexane at low pressure (3 Torr), containing multi-wire proportional chambers and a silicon semiconductor detector. Using this setup, alpha particles emitted during the decay of the radioactive isotope 226Ra were detected. The device has an energy resolution of ≤ 5% and allows measuring the ionization energy losses of alpha particles as well. Thus, the LPMWPC and SSD-based experimental setup is a good tool for studying both binary and ternary fission of heavy nuclei, in which the third fragment is a high-energy alpha particle.

We measure cross sections of proton-induced reactions on tin up to energies of 18 MeV using the stacked-foil activation technique, and report first experimental values for 114Sn(p,α)111In, 120Sn(p,α)117gIn, and 114Sn(p,x)113Sn reactions. Measured cross sections have been compared to existing experimental values and numerical calculations based on Talys1.95. Our data are in good agreement with all previous experiments, and also with Talys1.95 results except for 120Sn(p,α)117m,gIn reactions where the numerical calculations are shifted to higher energies. We also measure isomeric cross section ratios for 117m,gIn and 120m,gSb pairs as functions of the incident proton energy. [ABSTRACT FROM AUTHOR]

The nuclear reactions on zinc isotopes leading to the formation of the medical theranostic isotope 67Cu have been investigated. Model calculations were made using the TALYS1.9 code. The results are compared with the published experimental data. The comparison of calculated and experimental data showed a satisfactory agreement in the case of the proton-nuclear reactions. In the case of the calculations of the photonuclear reactions, the essential differences are observed at the maximums of the excitation functions. The calculated data in the case of the (γ, n) reactions do not reveal the widths and structure of the excitation functions. [ABSTRACT FROM AUTHOR]

The possibility of employing the isotope 96gTc as a gamma-ray emitter in medical diagnostics is examined. Corresponding calculations by the TALYS-1.9 revealed that an irradiation of a 96Mo target with protons of energy E =12 → 6 MeV at a current of 100 μA for six (eight) hours makes it possible to produce 20 (26) GBq of the isotope 96gTc. In detecting gamma rays of energy in the range between 770 and 850 keV, the intensity of gamma rays from 96gTc is close to their intensity for 99mTc obtained in the reaction 100Mo(p, n), so that one can use96gTc as an alternative gamma-ray emitter.

The possibility of 55Co and 124Sb radioisotopes production by CYCLONE C18/18 is discussed. Using 55Co in Positron Emission Tomography (PET) visualization seems attractive, and 124Sb can be used in Intra Vascular Brachytherapy (IVBT). Calculations by TALYS 1.6 code are performed for 58Ni(p, α)55Co and 124Sn(p, n)124Sb reactions and the obtained data are compared with the experimental ones from EXFOR data base.

The recoil properties of the product nuclei from the interaction of 2.2 GeV/nucleon 12C ions from Nuclotron of the Laboratory of High Energies, Joint Institute for Nuclear Research at Dubna with a 118Sn target have been studied via catcher foils method. The experimental data were analyzed using the mathematical formalism of the standard two-step vector model. The results for 12C ions are compared with those for deuterons and protons. Three different Los Alamos versions of the Quark-Gluon String Model were used for comparison with our experimental data. [ABSTRACT FROM AUTHOR]

The recoil properties of the product nuclei from the interaction of 3.65-GeV/nucleon protons and deuterons from the Nuclotron and Synchrophasotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR) at Dubna, with a 118Sn target have been studied using catcher foils. The experimental data were analyzed using the mathematical formalism of the standard two-step vector model. The analysis of kinematical characteristics of the light and medium-mass reaction products confirmed the contribution of fragmentation (or multifragmentation) processes in the production of these nuclei. The comparison of the results for protons and deuterons was made. The longitudinal momenta transferred to the target in the interaction with protons and deuterons were similar and was shown to depend only on the velocity, but not on the mass of projectile. Three different Los Alamos versions of the quark—gluon-string model (LAQGSM) were used for the discussion of our experimental results. [ABSTRACT FROM AUTHOR]

Photonuclear reactions on titanium targets of natural composition at the bremsstrahlung endpoint energy of 30 and 40 MeV have been investigated. The yields of 47 Sc at the end of the bombardment were measured to be (0.45 ± 0.07) MBq/(μA h g) and (1.34 ± 0.12) MBq/(μA h g) for 30 and 40 MeV, respectively. Cross-sections per equivalent quantum of the reactions nat Ti(γ,x) 43,44m,44g,46,47,48 Sc and nat Ti(γ,xn) 45 Ti were measured., (Copyright © 2022 Elsevier Ltd. All rights reserved.)
