Description

The medium effect of in-medium nucleon–nucleon cross section σNNmed(αm) on the isoscaling parameter α is investigated for two couples of central nuclear reactions 40Ca+48Ca and 60Ca+48Ca; 112Sn+112Sn and 124Sn+124Sn at beam energy region from 40 to 60 MeV/nucleon with isospin dependent quantum molecular dynamics. It is found that there is the obvious medium effect of σNNmed(αm) on the isoscaling parameters α. The mechanism for the medium effect of σNNmed(αm) on α is investigated. (author)
