Potential energy of electron

  1. Feb 2, 2007 #1
    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?

    "How we can measure it?" You can't place an electron at point r to measure
    -e^2/r, but there are other ways to measure that V=-e^2/r is correct.
    It leads to the experimental BE and energy levels of hydrogen and to the correct experimental e-p scattering.
    This can be considered a measurement that V= -e^2/r is correct.

    Can you post me some links for this problem.
    What is BE? May be Bose-Einstein?
    How we can solve Schrodinger equation which have given wave function , but unknown pot. energy?

    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.

    Eigenstates are known. Unknown is only U(x).

    I think Meir means "binding energy", that is, measurements of the ionization energies of hydrogen atoms.

    Of course, it's "binding energy". I didn't guess right.
