Ml. Ge et al., Unified approach for exactly solvable potentials in quantum mechanics using shift operators - art. no. 052110, PHYS REV A, 6205(5), 2000, pp. 2110
We present a unified approach for solving and classifying exactly solvable
potentials. Our unified approach encompasses many well-known exactly solvab
le potentials. Moreover, our approach can be used to search systematically
for a new class of solvable potentials.
