A What are L+ and L- matrices for l=3 ?

  1. Jan 9, 2017 #1
    Hi everyone
    I need raising and lowering operators for l=3 (so it should be 7 dimensional ).
    is it enough to use this formula:
    (J±)|j, m > =sqrt(j(j + 1) - m(m ± 1))|j, m ± 1 >
    The main problem is about calculating lx=2 for a given wave function , I know L^2 and Lz but I need L+ and L- to solve the problem.
    Thanks in advance

    Yes, you can use that formula. Matrix elements for an operator ##\hat{A}## are simply given by
    $$
    A_{ij} = \langle i | \hat{A} | j \rangle
    $$
