Parity of two body system

  1. May 25, 2008 #1
    I'm confused about how parities 'add up'.
    (I'm using the shell model of a nucleus)
    If you have e.g.a neutron in a d state (so l=2) and one in a p state (l=1), what is the parity of the total system? Do you have to multiply (+1*-1=-1?) or add the l values or something completely different?

    Hey
    The parity [tex]\pi[/tex] for a state is [tex](-1)^{l}[/tex] The total parity is
    [tex]\pi_{1}*\pi_{2}[/tex] or
    [tex](-1)^{l_{1}+l_{2}}[/tex]

    Yes, parities are multiplied.
