Homework Help: Shell Model

  1. Jun 1, 2010 #1
    1. The problem statement, all variables and given/known data
    How do 5 protons fill a g9/2 shell in the shell model?
    There are 10 spots in the g9/2 shell.

    2. Relevant equations

    3. The attempt at a solution
    Pauli principle dictates the first four to be in anti-parallel pairs. But the last can be either up or down. Am I missing something or is this really all there is to it?

    I will try to go a little further in hope that someone picks it up and can help me.
    I think I need to find the state of minimal energy for the last neutron. What are the assumptions I need to make to calculate this? Is it good enough to assume the complete independent particle model?

    I really could use some help on this one. I can do the opposite, get total spin of nucleus in the groundstate by the nucleonconfiguration, but the reverse is not so clear for me...

    I am still wondering btw... :p
