Abstract
I investigate a recently developed method for obtaining bound-state eigenvalues of anharmonic oscillators, and from it derive useful approaches that converge faster. The method consists of writing the eigenfunction as an exponential of a polynomial times a power series, in which the former factor is properly chosen to simplify the resulting recursion relations for the coefficients of the expansion. I also apply the method to central-field models.Keywords
