Global features of dissipative processes in light heavy-ion collisions

摘要: Abstract The 19 F + 27 Al and 12 C collisions at incident energies of 111.4, 125, 136.9 MeV respectively, have been studied. Continuous energy angular distributions for 5≤ Z ≤16 reaction products measured. correlations between different physical observables show similar trends with the case much heavier interacting systems. Thus, a complete dynamics, from quasielastic to dissipation regime, is evidenced also in reactions light nuclei. interaction time, extracted experimental distributions, increases increasing total kinetic loss 10 −23 s up −21 s. Based on simple assumptions about underlying microscopic mechanisms, semiempirical relationships are suggested applied account systematic features element measured light-, medium- heavy-nuclei collisions. Absolute cross sections nonfusion processes deduced data. Comparison dynamical models presented.
