Determination of neutron-skin thickness using configurational information entropy

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