Thank you so much! Great example!

This does not make sense! (KE+PE)(psi) = KE (psi) + PE (psi), It does matter that eigenfunction has to be an eigenfunction of both KE and PE.

No - I don't. Is the answer to my question in functional analysis?

The sum doesn't matter. The thing is (KE+PE) psi is a wrong expression - since KE and PE operators have to have different wave functions. Yet, in every single quantum chemistry text it is this (KE+PE) psi that is solved for the hydrogen atom!

Hi All, Perhaps I am missing something. Schrodinger equation is HPsi=EPsi, where H is hamiltonian = sum of kinetic energy operator and potential energy operator. Kinetic energy operator does not commute with potential energy operator, then how come they share the same wave function Psi? The...
