抄録

Cross sections and mean projected ranges of the recoil ions for ²⁰⁹Bi(p, n) reaction with E_p from 18 MeV to 64 MeV were obtained. The cross sections were analysed both by the hybrid model and by the geometry dependent hybrid model. The geometry dependent hybrid model was found to reproduce the experimental (p, n) cross sections upto E_p of 64 MeV, while the calculated cross sections by the hybrid model deviate from the experimental ones at the proton energies higher than 40 MeV. Dependence of decay rates of the exciton states on the nuclear density was discussed and it was concluded that the pre-compound model is essentially concerned with averaging of the doorway states. Recoil ranges of the reaction residuals were analysed, introducing a 90° asymmetry term P₁(cos θ) for the angular distributions of the residuals in CM system.
