Abstract:

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 140A MeV 40,48Ca + 9Be and 58,64Ni + 9Be reactions,
and the calculated 80A 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.

Key words: Isobaric yield ratio difference, Symmetry energy, Neutron density, Neutron-rich nucleus
