The energy levels of U4+ have been analysed using a ten-parameter Hamiltonian and, in particular, the effect of the magnetic and configuration interactions is examined. Bivariate polynomials of double Chebyshev series for each energy level are derived in terms of Marvin integral M0 and configuration interaction parameter a. A diagram showing transition from LS to jj coupling is given. © 1995 Società Italiana di Fisica.
