Abstract

Coulomb barrier height is a basic parameter to describing the nuclear reactions. Recently it is found that ions produce from nuclear reactions can be used to study electron loss and capture processes. Hence determining the Coulomb barrier becomes important in both nuclear and atomic physics. The different models depend on the nucleus-nucleus potential chosen or parameters used to calculate the barrier heights. In this work we plan to develop a parameterized formula from experimental results obtained from quasi elastic scattering. Since quasi elastic data spread over Z1Z2=64 to Z1Z2=2460, the formula is expected to work in the range of low Z1Z2 to high Z1Z2, where Z1, Z2 are the atomic number of the projectile and the target, respectively.
