We apply conservation laws of angular momentum and parity, along with Pauli statistics, to determine which final NN state is not allowed. The final state must satisfy the condition T(NN) = S(NN) + L(NN) + 1 (mod 2) and must also respect the conservation of angular momentum and parity. The answer indicates that the transition from 1S0 to 3P0 + s is not permitted due to these constraints."}
