Abstract
A semi-microscopic analytical expression of the nucleus-nucleus total reaction cross section (ÏR) was proposed based on the strong absorption model. It is suitable for stable nuclei at intermediate energies. The matter density distributions of nuclei and the nucleon-nucleon total cross section were both considered. Particularly, the Fermi motion effect of the nucleons in a nucleus was also taken into account. The parametrization of ÏR was applied to the colliding systems including 12C. The experimental data at energies from 30 to 1000â¯MeV/nucleon were well reproduced, according to which an approach of deriving ÏR without adjustable parameters was developed. The necessity of considering the Fermi motion effect in the parametrization was discussed.
