Configurational information entropy analysis of fragment mass cross distributions to determine the neutron skin thickness of projectile nuclei
文献摘要：
Configurational information entropy(CIE)analysis has been shown to be applicable for determining the neutron skin thickness(δnp)of neutron-rich nuclei from fragment production in projectile fragmentation reactions.The BNN+FRACS machine learning model was adopted to predict the fragment mass cross-sections(σA)of the projectile fragmentation reactions induced by calcium isotopes from 36Ca to 56Ca on a 9Be target at 140 MeV/u.The fast Fourier transform was adopted to decompose the possible information compositions in σA distributions and determine the quantity of CIE(SA[f]).It was found that the range of fragments significantly influ-ences the quantity of SA f],which results in different trends of SA[f]～δnp correlation.The linear SA[f]～δnp correla-tion in a previous study[Nucl.Sci.Tech.33,6(2022)]could be reproduced using fragments with relatively large mass fragments,which verifies that SA f]determined from fragment σA is sensitive to the neutron skin thickness of neutron-rich isotopes.
