Abstract
High-spin states in Pm-143 have been investigated via the Te-128(F-19, 4n g amma) Pm-143 reaction using techniques of in-beam gamma -spectroscopy. gamm a -ray singles, gamma-gamma coincidences, gamma -ray anisotropies and DCO r atios have been measured. Based on these measurements, the level scheme of Pm-143 has been extended up to excitation energy of 10535. 4keV including 3 2 new gamma rays deexciting of 17 new levels. The yrast levels in Pm-143 ca n be understood qualitatively in the framework of a weak-coupling model.
