    "abstract": "In the single j shell there is a two to one relationship between the spectra\nof certain even-even and neighbouring odd mass nuclei e.g. the calculated\nenergy levels of J=0^+ states in ^{44}Ti are at twice the energies of\ncorresponding levels in ^{43}Ti(^{43}Sc) with J=j=7/2. Here an approximate\nextension of the relationship is made by adopting a truncated seniority scheme\ni.e. for ^{46}Ti and ^{45}Sc we get the relationship if we do not allow the\nseniority v=4 states to mix with the v=0 and v=2 states. Better than that, we\nget very close to the two to one relationship if seniority v=4 states are\nadmixed perturbatively. In addition, it is shown that the higher isospin states\ndo not contain seniority 4 admixtures.",
