Main Question or Discussion Point
It is known that the potential energy of electron in the hydrogen atom is completely definite quantity, for given point . How we can measure it?
I'm no expert on QM, but isn't the answer to this question simply, "you...can't!" I mean, if the Hamiltonian is not fully-defined, then you can't solve for its eigenstates.How we can solve Schrodinger equation which have given wave function , but unknown pot. energy?
