Theoretical quantum mechanics problem

  1. Mar 27, 2009 #1
    1. The problem statement, all variables and given/known data
    Demonstrate that <[tex]\alpha_{1},j_{1},m_{1}|r·p+p·r|\alpha_{2},j_{2},m_{2}>[/tex] is 0 when [tex]m_{1}\neq m_{2}[/tex]


    2. Relevant equations



    3. The attempt at a solution
    I have demonstrated that r·p+p·r is equal to [tex]\frac{i·m}{\hbar}[H,r^{2}][/tex]

    I would appreciate your help. Thank you
