Method of correlated quasiparticles. III. 0+ particle--particle residual interactions in odd-mass systems

Methods are developed for determining the properties of low-lying states in odd-mass systems with a residual interaction of the 0⁺ particle-particle form. Using matrix elements obtained from a surface-peaked δ interaction, the methods of this paper are applied to an analysis of states in ²³⁵U and ²³⁷U. 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.[NUCLEAR STRUCTURE: Quasiparticles; residual interactions; ^235,phantomrule0ex0ex237U calculated levels.]
