These new empirical formulae depending on the asymmetry parameters (s = (N - Z)/A) were determined by using the least squares approximation fitting method to the available experimental cross section data taken from EXFOR. The results have been compared with the experimental data and found to be well in agreement.eninfo:eu-repo/semantics/closedAccessEXFOREmpirical formulaCross-section(gamma .
