Abstract
High-spin states in Pm-143 have been investigated via the Te-128(F-19,4n ga mma)Pm-143 reaction using techniques of in-beam gamma -spectroscopy, gamma -ray singles, gamma-gamma coincidences, gamma -ray anisotropies and DCO rat ios have been measured. Based on these measurements, the level scheme of Pm -143 has been extended up to an excitation energy of 10535.4 keV, including 48 new gamma -rays deexciting 28 new levels. The yrast levels in Pm-143 ca n be understood qualitatively in the framework of a weak-coupling model.
