Abstract

Using the configuration interaction Hartree–Fock method, the even and odd Hamiltonian matrices of Sm IX are studied in the ls and j j coupling schemes. Sm IX is isoelectronic with Xe but because of 4f orbital contraction, and the near degeneracy of 4f and 5p binding energies, the lowest configuration is a mixture of states with differing numbers of 4f and 5p electrons. Diagonalization of the Hamiltonian results in a set of eigenvalues and eignvectors which are characterized using various statistical tests of random matrix theory.
