Nuclear physics: shell model

  1. Nov 8, 2013 #1

    Just a quick question that I have been wondering about ... how do nucleons fill energy levels, and what is the maximum number of nucleons that can occupy each level?

    The given pattern is:

    1s, 1p, 1d, 2s, 1f, 2p, 1g, etc

    I can see no obvious pattern here. Can anyone explain? I think I may be missing some kind of fundamental point!

    There is no simple pattern. Number of particles per shell is the same as in electron orbitals, though. You can have two protons and two neutrons in s orbitals, six of each in p, and so on. This is true for any kind of fermion in any central potential.
