Abstract
A more general treatment than has been available of the Wentzel-Brillouin-Kramers method of solving Schrödinger's equation for one degree of freedom is given. Wentzel's original energy-level condition is shown to be an asymptotic expression, good for large masses and large values of the quantum number. The connection between this method and that of Young is discussed. Finally the formulas are written in a form convenient for application to the calculation of energy levels from actual potential functions.Keywords
