The aim of this paper is to investigate a new parametrization for the matrix, set up on the states of an open (nuclear or atomic) shell, of any two‐body interaction expandable in multipoles. Such a parametrization is particularly convenient for expressing the term energies in a simple form and for producing high degeneracies among the terms. Further, the parametrization considered allows the two‐body interaction to be decomposed into a Dirac interaction and a remaining part.
