The calculation of total reaction cross sections induced by intermediate energy α-particles with BUU Model
Abstract
The Boltzmann-Uehling-Uhlenbeck (BUU) Model, which includes the Fermi motion, the mean field, individual nucleon-nucleon (N-N) interactions and the Pauli blocking effect etc., is used to calculate the total reaction cross section σR induced by α-particles on different targets in the incident energy range from 17.4 to 48.1 MeV/u. The calculation result can reproduce the experimental data well. The nucleus-nucleus interaction radius parameter r0 was extracted from experimental σR. It is found that r0 becomes constant with increasing the mass number of target.
