Urgent help needed related Nuclear Physics ! Thanx

1. According to the shell model determine total angular momentum and parity of lowest energy state of 15N, 1Ne, 15C, 2Ti, 14ZRh 103 5. According to the nuclear shell model, determine total angular momentum and parity of lowest energy state of proton and first excited state of proton of next cores: 15N, 1B,Na,P, 7. According to the shell model, sort next isotopes according to the maximal angular momentum they can have in the ground state (write the angular momentums.) 15N, 1AL $9Са, 79Со, 199Ru 36 15P 2Sc, 5Mu,

Answer 1

This method 'Shell Model is only applicable for singly unpaired nucleon,that too of same type i.e either Proton or neutron.

When 2 nucleons are unpaired, Shell model is not applicable.

The level scheme is provided on right.

J gives Angular momentum while π gives parity and its representation is (J)^π .
