Description
The structure of /sup 145/Pr has been investigated by measuring the gamma-ray singles, gamma-ray coincidence, and gamma-ray angular correlation spectra, along with conversion-electron singles spectra for the decay of 3.0-min /sup 145/Ce to levels of /sup 145/Pr. A level scheme is proposed that includes a number of new levels as well as new spin and parity assignments for several levels. The conversion-coefficient measurements establish the presence of a low-energy (3/2-) level at 787 keV whose strong population in beta decay confirms negative parity for the ground state of /sup 145/Ce. Interacting boson-fermion model calculations for /sup 143/Pr and /sup 145/Pr are found to be in reasonable agreement with the observed low-energy positive-parity levels, while the presence of the low-energy (3/2-) level suggests the coexistence of more deformed configurations
