The asymptotic iteration method for the angular spheroidal eigenvalues with arbitrary complex size parameter c

The asymptotic iteration method is applied to calculate the angular spheroidal eigenvalues. lambda(m)(l)(c) with arbitrary complex size parameter c. It is shown that the numerical results obtained for. lambda(m)(l)(c) are all in excellent agreement with the available published data over the full range of parameter values l, m, and c. Some representative values of. lambda(m)(l)(c) for large real c are also given.
