Abstract : The previously reported levels and assignments to 151,152,153Pr have recently been called into question about the mass assignment to the reported bands. Recently prompt γ-rays in coincidence with isotopically-identified fission fragments using VAMOS++ and EXOGAM, produced using 238U on a 9Be target have been reported. To clarify the recently questioned mass assignments of 151,152,153Pr, the γ-γ-γ-γ data from 252Cf (SF) by using Gammasphere and the GANIL in-beam mass- and Z-gated γ-spectra were combined to assign transitions and levels in these Pr isotopes. The transitions and levels previously assigned to 151,153Pr have been confirmed by the M-Z gated spectra. The transitions previously assigned to 152Pr are now assigned to 151Pr by using the M-Z gated spectra. Three new bands with 24 new transitions in 152Pr and one new band with 7 new transitions in 153Pr are identified. The Yttrium fission partners of all the 151,152,153Pr have Gaussian yield distributions that peak at the 3n channel.
