The β+ decay of 127,126,125Pr was studied for on-line mass-separated sources. The decay scheme of 127Pr reported previously was revised from the results of a more-detailed analysis of the experimental data. The 125Pr isotope was newly identified with a half-life of 3.3(7) s and its decay scheme is presented. The γ band in 126Ce was identified in the decay of 126Pr and its properties are compared with the prediction of the interacting boson model 2.
