Isospin effects in 40,48Ca+40,48Ca collisions

Abstract : The isospin dependence of two proton correlations is studied in 40Ca+40Ca and 48Ca+48Ca collisions at E/A = 80 MeV. Measurements were performed with the HiRA detector array complemented by the 4π Ball at NSCL. We observe a strong isospin dependence of the ppcorrelation functions; however the emitting source radius extracted using the imaging technique yields no sensitivity to the isospin of the reaction system. We interpret this result as a consequence of smaller fraction of fast proton emission in the neutron rich 48Ca system.
