Effect of Centrifugal Term Approximation on Short Range Potential

Abstract

The strength of linear combined short-range potential (Yukawa plus Hulthen) is calculated using two different centrifugal term approximation (equation 2 and equation 3). The calculation shows that the strength of potential calculated using an approximation of equation (3) is greater than equation (2), but the difference between them is negligible. Therefore, both approximation is used to calculate the energy eigenvalue of considering a potential system. Besides also, the functional value goes decreasing with increasing screening parameters and nucleon separation distance. This decreasing functional value shows the nature of potential Yukawa plus Hulthen potential is short-range potential.
