While solving the Schrodinger equation for Hydrogen atom, we use the reduced mass and get the wave functions of the electron. I like to get the wave functions of the nucleus as well as that of the electron. This may probably need to avoid using the reduced mass concept. Is this problem analytically solvable? If so, where can I find the solution? If it is not analytically solvable, where/how can I get the numerical solution? Thank you.
