  "abstract": "It was found previously that in the system of four particles of the same kind in an angular momentum $j = 9/2$ shell, the energies $E_I$ of four particular levels with angular momenta $I = 4$, 6, 10, and 12, are related by $E_I = a + b I(I+1)$, where $a$ and $b$ depend only on the two-body interaction. Here, I discuss observable implications of this regularity and analyse in detail its origin.",
