The decay of Pr137 entirely to a 9.0-hour ground state of Ce137 was independently discovered. By allowed electron capture, Ce137 decays predominantly to a low-lying state of La137, with only a 3% branching to a 440-kev excited state. The 440-kev transition is at least predominantly E2 in character.A 34.4-hour isomeric state produced by the La139(p, 3n)Ce137m reaction decays by a 254.5-kev M4 transition to the 9-hour -ground state. A 0.6% branching was found from the isomeric state directly to a small group of apparently high spin states in La137.Studies of mass-separated isotopes confirmed the existence of 1.5-hour Pr137 and 1.0-hour Pr136. The K-capture to positron branching ratios observed in the decay of Pr139, Pr138, Pr137, and Pr136 show that these isotopes decay by allowed transitions to their cerium daughters. Characteristic gamma rays were observed.

High spin states in 147Tb have been excited by means of the 144Sm(6Li,3n) reaction and studied by means of γ-ray and electron measurements. Gamma-ray singles, excitation functions, angular distribution, linear polarization, γ–γ coincidence, and internal conversion measurements have been made. These have led to unambiguous spin and parity assignments to many levels and to lifetime determinations for two states. The resulting level scheme is discussed and compared with recent calculations.
