    "abstract": "We provide some explicit examples wherein the Schr\\\"odinger equation for the\nMorse potential remains exactly solvable in a position-dependent mass\nbackground. Furthermore, we show how in such a context, the map from the full\nline $(- \\infty, \\infty)$ to the half line $(0, \\infty)$ may convert an exactly\nsolvable Morse potential into an exactly solvable Coulomb one. This generalizes\na well-known property of constant-mass problems.",
