Phenomenological formula of total reaction cross sections for low-energy systems

Abstract

This Brief Report presents a phenomenological formula of total reaction cross sections for different reaction systems at low energies, taking into account the case of weakly bound nuclei as projectiles. To get this phenomenological formula, a large set of experimental data were collected and compared. Based on the experimental total reaction cross sections, three parameters were used to modify Wong's formula. The total reaction cross sections of different systems at low energies including weakly bound projectiles were reproduced using the modified formula.
