摘要:

A simple approximate method based on variational principles is used to obtain energy eigenvalues for bound quantum systems. It is shown that the approximate eigenvalues satisfy both virial and Hellmann–Feynman theorems. Results obtained by this method are compared with the exact solutions of the Schrödinger equation.
