摘要

Configurational information entropy (CIE) the-ory was employed to determine the neutron-skin thickness of neutron-rich calcium isotopes.The nuclear density dis-tributions and fragment cross sections in 350 MeV/u 40-60Ca + 9Be projectile fragmentation reactions were calculated using a modified statistical abrasion-ablation model.CIE quantities were determined from the nuclear density,isotopic,mass,and charge distributions.The linear correlations between the CIE determined using the iso-topic,mass,and charge distributions and the neutron-skin thickness of the projectile nucleus show that CIE provides new methods to extract the neutron-skin thickness of neutron-rich nuclei.
