Projectile fragmentation in nuclear reactions at fermi energies

In this short communication, we have interpreted TAMU data for peripheral collisions of 40Ca + sSn and 48Ca + 112;124Sn at E=A = 32 MeV with different isospin degrees of freedom which were studied at the Cyclotron Institute of Texas A and M University (TAMU) using the K500 Superconducting Cyclotron. Isotopic yields of light intermediate mass fragments Z ≤ 8, (here, we only consider carbon isotopes) were studied on the basis of the statistical multifragmentation model. It is seen from the fractional yields that the neutron-rich systems preferentially populate the most neutron-rich isotopes. It is confirmed that symmetry energy is the main parameter governing the isotopic composition of the fraction yields.
