Yield ratios and directed flows of light fragments from reactions induced by neutron-rich nuclei at intermediate energy
The yield ratios of neutron/proton and ^3H/^3He and the directed flow per nucleon for these projectile-like fragments at large impact parameters are studied for ^50Ca + ^40Ca and ^50Cr + ^40Ca for comparison at 50 MeV/u using the isospin-dependent quantum molecular dynamics(IQMD model.It is found th...

Summary: | The yield ratios of neutron/proton and ^3H/^3He and the directed flow per nucleon for these projectile-like fragments at large impact parameters are studied for ^50Ca + ^40Ca and ^50Cr + ^40Ca 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 ^50Ca and the stable isobaric nucleus ^50Cr,and depend on the hardness of the EOS.The ratios of neutron/proton and ^3H/^3He and the difference of directed flow per nucleon of neutron-proton are suggested to be possible observables to investigate the isospin effects. |
