Direction for an electron in the 1s orbital of Hydrogen be?

  1. Feb 26, 2004 #1
    What would the value of linear momentum in the r direction for an electron in the 1s orbital of Hydrogen be?

    Is this an expectation value or eigenvalue?

    Re: eigenvalues

    I really think you should be doing yer own homework :wink:, but I'll give a little hint. Linear momentum is pψ=i(hbar)gradψ. Use the appropriate component.

    The eigenvalues ai of an operator A corresponding to states ψi are defined by:

    Aψi=aiψi.

    The expectation value of an operator A in state ψi is defined by:

    ∫ψ*Aψd3x

    Can you figure out which one you have here?
