Using analytical transfer matrix (ATM) theory, the phase contribution devoted by the scattered subwaves is found to be independent of n and integrable for all known shape invariant potentials (SIPs) with translation. We also successfully explain why SWKB quantization condition yields exact bound-state spectra for all SIPs.
