| Abstract: | A simple phase correction is derived for the coupled-states (CS) approximation based on WKB phase shifts for the electric part of the potential. The resulting phase-corrected CS (PCCS) scattering matrix agrees well in both phase and magnitude with the exact one. The PCCS approximation should then give accurate m-state information for any quantization axis. |
