A simple weak coupling model previously applied to the analysis of the yrast spectrum of {sup 143}Nd is extended to yrast spectra of odd-{ital A} {ital N}=82 and 83 isotopes of {ital Z}=58--61 nuclei. The model generally provides a good description of these spectra; however, yrast 19/2{sup +} states expected to arise in {sup 141}Pr and {sup 143}Pm from the coupling of {pi}{ital g}{sub 7/2} holes to the 6{sub 1}{sup +} states of the even-even cores are not observed experimentally. The absence of these states can be explained using a simple microscopic argument.
