Nucleon transfer in highly mass-asymmetric reaction systems between 197 Au and relatively light projectiles in the energy region below 10 MeV/u

摘要: Mechanisms of heavy-ion induced nuclear reactions in mass-asymmetric systems were studied by focusing on the nucleon transfer reaction. Excitation functions and projected mean recoil ranges for target-like products in37-,16O-,14N-, and12C-induced on197Au measured means ofγ-ray spectrometry. The energy range was near Coulomb barrier with incident energies below 10 MeV/u. Nucleon discussed distinguishing from quasi-elastic (QET) those deep inelastic (DIT). tendency towards equilibration theN/Z value damping, which are characteristic features DIT, found production Au isotopes. Observations consistent generally accepted concept that QET takes place along a trajectory trajectory. made to be connected interaction radius most cross section ratios reproduced well an extended tunneling model.
