Abstract：
Yields have been measured with good Z and A resolution for Xe-like fragments produced in quasielastic and partial damped reactions of 5.9 MeV/N ¹²⁹Xe ion bombarding ⁵⁶Fe, ¹²⁴Sn, ¹¹⁶Sn targets and 5.8 MeV/N ¹³⁶Xe ion bombarding ⁵⁶Fe target. The relationship between the variance of the mass and charge distributions are found to depend on the degree of energy damping and the system. The relationship of the correlation coefficients ρ with the energy damping are also obtained. It is found that the correlation coefficients ρ is bether quantity to express the degree of correlation between neutron and proton exchange than σ²_A/σ²_Z.
