Homework Help: Angular momentum of electron

  1. Aug 18, 2012 #1
    1. The problem statement, all variables and given/known data
    What is the significance of quantization of angular momentum in the absence of magnetic field?


    2. Relevant equations
    Lz=mlh/2∏;Jz=mjh/2∏;Sz=msh/2∏.


    3. The attempt at a solution
    I read that in the absence of magnetic field,z-axis direction is arbitrary and the component of L along whatever direction we choose must be mlh/2∏.How can this be true?Moreover I think, say in 2p state,each of the 3 ml values(-1,0,1)are assigned to uniquely to each of 2px,2py and 2pz.This is also not in accordance with space quantization concept.
    Please anyone explain this to me.
