Approximate l-States of the Manning-Rosen Potential by Using Nikiforov-Uvarov Method

Figure 2

A plot of the variation of the singular orbital term 1/𝑟² (dotted-solid line) with the approximations of (a) [17, 18] (dash line), the conventional Greene-Aldrich of [19] (dash-dot line), and improved [23, 96–98] (solid line) replacing the term 1/𝑟² with respect to 𝑟, where 𝛿=0.1fm⁻¹, and (b) the improved approximation [96–98] with various shifting constants.
