A correlation consistent basis set, through g functions, is developed for uranium. Calculations are carried out for U(BH4)4 using a relativistic effective core potential and the spin-orbit effect included at the configuration interation level. The calculated electronic energy levels are compared with experimental data and previous assignments and calculations. The effect of basis set size on f->f excitation energies is discussed.
