The link between the Milne phase‐amplitude formulation and the semiclassical treatment of the wave equation is explored. An improved strategy for integrating the Milne equations is derived and illustrated with the double‐well, harmonic‐oscillator, and Coulomb potentials.
Keywords: wave equation, phase amplitude, semiclassical methods
