I Electron wavefunction as an overlap of orbitals

  1. Jun 4, 2017 #1
    so im finishing up my studies of intro to quantum mechanics, and this is not in my book and looking at previous exams i have to know this for single electron atoms/ions.
    one of the problems was somethin like
    "the wave function of an electron is the overlap of the orbitals:
    find avg energy. what is the probability of measuring it?"
    i dont want help solving this, can you just point me to an website/book that covers this? thank you

    "Something like" or "exactly like"? If I'm understanding the question properly by reading "overlap" as "superposition", it only makes sense for one particular value of ##a##. And (again, if I'm understanding the question properly) the answer is going to be in your book - somewhere it will talk about expectation values of measurements.

    I wouldn't call it the "overlapp" but a superposition. The orbitals making up the superposition are orthogonal, so technically, they have no overlapp.

    thanks for yur answers sorry about the overlap thing it was a translation problem.
    and the problem i presentd was in an actual exam but all of them always have a problem like that.
    im gonna take a carefull look at both books ive got
