摘要
The yield ratios of neutron/proton and H-3/He-3 and the directed flow per nucleon for these projectile-like fragments at large impact parameters are studied for Ca-50 + Ca-40 and Cr-50 + Ca-40 for comparison at 50 MeV/u using the isospin-dependent quantum molecular dynamics (IQMD) model. It is found that the yield ratios and the directed flows per nucleon are different for reactions induced by the neutron-rich nucleus Ca-50 and the stable isobaric nucleus Cr-50, and depend on the hardness of the EOS. The ratios of neutron/proton and H-3/He-3 and the difference of directed flow per nucleon of neutron-proton are suggested to be possible observables to investigate the isospin effects.
