Inelastic excitation and nucleon transfer in quasielastic reactions between86Kr and208Pb at 18.2 MeV/u beam energy

Abstract

Angular distributions for inelastic scattering, for 1 and 2-nucleon transfer reactions were studied at 18.2 MeV/u beam energy. Owing to sequential decay of excited reaction products the nuclide yield measured at various angles and in different regions of total kinetic energy loss (TKEL) does not represent the yield of primordial nuclidesA Z. Monte Carlo calculations were applied in order to reconstruct the primary double-differential cross-sections d2σ/dΩdTKEL for values of TKEL up to 80 MeV. By comparing the probability of inelastic scattering and that of transfer reactions it is found that the former dominates for TKEL< 10 MeV, whereas the situation is reversed above 20 MeV. No evidence is found for the excitation of giant resonances with significant cross section.
