摘要
The ground energy and some low lying excited energies and the corresponding wavefunctions for the generalized Killingbeck potential are investigated within the context of the recently introduced differential quadratic method. Highly accurate energy eigenvalues and an excellent agreement were found compared with the power series expansion and the supersymmetric perturbation theory.
