Abstract

The cross sections of fragments (σ_f ) produced in the even ^36~52Ca projectile fragmentation reactions at 80 A MeV are calculated in the framework of the statistical abrasion-ablation model. The distributions of (σ_f ) are investigated. Linear correlations between the peak positions of the distributions and charge numbers of the fragment isotopes are found.
- heavy-ion collisions,
- neutron density distribution,
- neutron-rich nucleus
