  We recently formulated a rule for isomeric states for a system of 4 nucleons
with isospin T=1, namely that if the nucleons are in a single j shell then
states with angular momenta J=2 and J=(2j-1) are either isomeric or ground
states [ze12]. To show that this is a robust result, we here consider a new
interaction from the literature that was used to discuss even-even and odd-even
nuclei. We here apply it to an odd-odd nucleus.
