Heavy-ion reactions with particle transfer are studied using the distorted-wave Born-approximation formalism. Different forms of the distorting optical model potentials are introduced in the initial and final channels. The form factors of the reactions are presented explicitly using modified real Woods–Saxon potentials for the nucleus–nucleus bound-state interactions in the entrance and exit channels. The differential cross sections of heavy-ion transfer reations are calculated numerically using the double-folding model for distorting potentials with an effective density-dependent nucleon–nucleon interaction. The present analyses of the angular distributions introduce good descriptions of the experimental data. The observed backward oscillations are described successfully by the explicit inclusion of the density- and the parity-dependent terms in the distorting optical-model potential calculations. The values of the extracted spectroscopic factors and normalization coefficients obtained are reasonable.

The fragmentation of 213 MeV/nucleon 40Ar ions by 12C targets is described within the context of a simple abrasion–ablation fragmentation model. The abrasion part of the theory utilizes a quantum-mechanical formalism based upon an optical model potential approximation to the exact nucleus-nucleus multiple-scattering series. The ablation stage of the fragmentation is treated as a compound nucleus evaporation. The decay probabilities for the various particle emission channels are computed using the EVAP-4 Monte Carlo computer program. Predictions for production cross sections for isotopes of sulfur, phosphorus, silicon, and aluminum are made and compared with experimental data. The model is also used to compare predicted and experimental element production cross sections for 1.88 GeV/nucleon 56Fe colliding with 12C and 208Pb targets.
