High-spin states in {sup 107,108}Pd and {sup 109}Ag have been studied by charged-particle-{gamma}, {gamma}-{gamma}, and charged-particle-{gamma}-{gamma} coincidence measurements of heavy-ion fusion-evaporation reactions. The high-spin level schemes of these nuclides have been significantly extended and new deformed rotational bands have been found in each nuclide. These bands exhibit the general property of back bends corresponding to the rotational alignment of a pair of {ital h}{sub 11/2} quasineutrons. Band properties are compared with predictions of the cranked shell model and total Routhian surface calculations. The properties of the yrast and near-yrast bands of all three nuclides are generally consistent with predictions of moderate ({beta}{sub 2}{approx_equal}0.2) prolate deformation. {copyright} {ital 1996 The American Physical Society.}
