# Quantum Potential - how to find its eigenstates?

I am studying the Pöschl-Teller potential in spherical coordinates and doing a change of variable is enough to put it in another sort of differential equation and thus, obtain the solution.

The point is: how can I find the eigenstates of this potential?

The second answer is: the eigenstates of the potential must be the same to any solutions? For example, the solution in terms of Heun function, hypergeometric function, etc.

• I'm not sure I understand: the eigenstates are the solutions to the resulting Schrödinger equation. You make changes of variable to simplify the solution to the DE but the solutions are the solutions. – ZeroTheHero Jan 13 at 19:44
