Abstract
A variation-perturbation method is presented for obtaining approximate eigenvalues of quantum mechanical oscillators with the potential energy function V(x) = ax4 + cx2. Numerical results show that solution of a cubic equation can often yield energy differences between the levels accurate to better than 0.001%. The method is accurate for both high and low quantum numbers.
