摘要:

A variational approach to the calculation of the two lowest eigenvalues of Schrödinger’s equation for the double‐oscillator potential is presented. A family of two‐parameter double‐Gaussian trial functions provides an alternative to the exact series expansions for the energy eigenfunctions and yields energy estimates of high accuracy.
