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 ^(58.64)Ni + ~9Be reactions,and the calculated 80 A MeV ^(38-52)Ca +^(12)C reactions by using a modified statistical abrasion-ablation model,show the sensitivity of the IBD to the density differences between reactions.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 ^40.48Ca ＋ ^9Be and ^58.64）Ni ＋ ^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.
