Inhomogeneous isospin distribution in the reactions of Si-28+Sn-112 and Sn-124 at 30 and 50 MeV/nucleon Academic Article uri icon

abstract

  • We have created quasiprojectiles of varying isospin via peripheral reactions of [Formula Presented] and [Formula Presented] at 30 and 50 MeV/nucleon. The quasiprojectiles have been reconstructed from completely isotopically identified fragments. The difference in [Formula Presented] of the reconstructed quasiprojectiles allows the investigation of the disassembly as a function of the isospin of the fragmenting system. The isobaric yield ratio [Formula Presented] depends strongly on [Formula Presented] ratio of quasiprojectiles. The dependences of mean fragment multiplicity and mean [Formula Presented] ratio of the fragments on [Formula Presented] ratio of the quasiprojectile are different for light charged particles and intermediate mass fragments. Observation of a different [Formula Presented] ratio of light charged particles and intermediate mass fragments is consistent with an inhomogeneous distribution of isospin in the fragmenting system. 2000 The American Physical Society.
