Abstract

Yrast states in the neutron-rich 1433Si19 nucleus have been studied using binary grazing reactions produced by the interaction of a 215-MeV beam of 36S ions with a thin 208Pb target. An experimental setup that combines the large-acceptance magnetic spectrometer PRISMA and the high-efficiency γ-ray detection array CLARA was used in the experiment. Four new γ-ray photopeaks at energies of 971, 1724, 1772, and 2655 keV were observed and assigned to the 33Si level scheme. The experimental level scheme is compared with the results of 1ℏω p-sd-pf large-scale shell-model calculations using the recently developed PSDPFB effective interaction; good agreement is obtained. The structure of the populated states of 33Si is discussed within the context of an odd neutron coupled to states of the 32Si core.

Abstract

Fusion-evaporation cross sections were measured in the two systems $^(48)Ca$ + $^(90,96)Zr$ in an energy range from well below to well above the Coulomb barrier. The sub-barrier fusion of $^(48)Ca$ + $^(90)Zr$ is reproduced by coupled-channels calculations including the lowest quadrupole and octupole vibrations of $^(90)Zr$, and using a Woods-Saxon potential with a standard diffuseness parameter a = 0.68 fm. However, the fusion cross sections are overestimated above the barrier. The low-energy slope of the excitation function for $^(48)Ca$ + $^(96)Zr$ is steeper. This implies a larger diffuseness parameter a = 0.85 fm. Fusion cross sections are well fit in the whole energy range, and the effect of the strong octupole vibration in $^(96)Zr$ is predominant. The extracted fusion barrier distributions are reasonably well reproduced by calculations for both systems. A comparison with previous data for $^(40)Ca$ + $^(90,96)Zr$ is made in an attempt to clarify the role of transfer couplings in sub-barrier fusion.

Abstract

Multinucleon transfer reactions in $^{40}$Ca+$^{208}$Pb have been studied at bombarding energies close to the Coulomb barrier. Projectilelike fragments have been identified in nuclear mass and charge with a time-of-flight spectrometer. Angular and total kinetic energy loss distributions and inclusive cross sections have been compared with those of semiclassical models. The analysis shows that a successive transfer mechanism of single nucleons does not account for the data, and a direct nucleon pair transfer has to be included in the description. Nucleon evaporation effects are taken into account.
