Abstract
The asymptotic iteration method (AIM) is used to accurately calculate the eigenvalues of the Schrödinger equation with the potential \(V(r)=-r^{-s}\), \(s\in (0,1),\) in arbitrary dimensions. The recently studied case, \(s=1/2\), is discussed in detail where we give a reason for non-polynomial solutions. Using AIM sequences, we develop a method to compute the coefficients of the series solution in this case. AIM applications for \(s=1/3,s=1/4\) and \(s=2/3\) are also discussed.
