Methods are developed for determining the properties of low-lying states in odd-mass systems with a residual interaction of the particle-particle form. Using matrix elements obtained from a surface-peaked interaction, the methods of this paper are applied to an analysis of states in and . The results are compared with equivalent pairing-force model calculations. Substantial differences, on the order of 300 keV, are found in the single-particle energy level spectra deduced from the two residual interactions.
