Recent experimental data on positive-parity yrast states, based on {pi}{ital h}{sub 11/2}{circle_times}{nu}{ital h}{sub 11/2} configuration, of odd-odd {sup 132,134,136,138}Pr nuclei have been analyzed in a systematic way with the energies and transition probabilities calculated within the framework of two quasiparticles coupled to an axially symmetric core model. It is found that very good agreement is obtained in {sup 132}Pr assuming a prolate deformation. For {sup 134,136}Pr also our calculation favors a prolate shape up to a quite high spin. Theoretical electromagnetic transition properties for both positive and negative deformation have been predicted for {sup 138}Pr. {copyright} {ital 1996 The American Physical Society.}
