A nuclear density probe: isobaric yield ratio difference 后印本

摘要: We report our recent progress on the nuclear symmetry energy probe, which is called the isobaric yield ratio difference (IBD), and its application in neutron density determination in experiments. The results obtained by the IBD, from which the isobaric yields in the measured 140 A MeV ^{40, 48}Ca + ⁹Be and ^58,64Ni + ⁹Be reactions, and the calculated 80 A MeV ^38-52Ca + ¹²C reactions by using a modified statistical abrasion-ablation model, show the sensitivity of the IBD to the density differences between reactions.
