CALCULATION OF CHARGE RADIUS OF NUCLEI USING THE MODIFIED COULOMB ENERGY FORMULA FOR NUCLEI

Abstract

Nuclear charge radius is an important macroscopic variable that determines the magnitude and extent of the Coulomb potential within the boundaries of the atomic nucleus. An expression for the modified Coulomb potential valid for the atomic nucleus has been used to obtain an expression for the nuclear charge radius. The calculated values for the nuclear charge radius have been compared with the experimentally observed values for the nuclear charge radius. Excellent agreement between the calculated nuclear charge radius and the experimentally observed nuclear charge radius leads to a modified Coulomb potential relation that can be used to calculate more accurately the binding energy for the nucleus. The average deviation of nuclear charge radius is calculated for 957 nuclei to establish the better agreement between the calculated nuclear charge radius and the experimentally observed nuclear charge radius and the value of the average deviation is 0.30297fm, which is small.
