1. STUDY OF EXCITED-LEVELS IN PM-147

Subjects
MEASURED GAMMA-GAMMA-T, R(DCO), INTRINSIC REFLECTION ASYMMETRY, 3N), 4N), MULTIPARTICLE CONFIGURATIONS, NUCLEI, ICC, E=18 MEV, E-GAMMA, PI, OCTUPOLE DEFORMATION, BRANCHINGS, E=78 MEV AND ND-148(D, REGION, I-GAMMA, T-1/2, XE-136(N-15, PM-147 DEDUCED LEVELS, GAMMA-RAY INTENSITY
Abstract

Excited states in Pm-147 have been studied through the Xe-136(N-15,4n) and Nd-148(d,3n) compound nucleus reactions. A solid xenon target has been used to populate high-spin states in Pm-147. Conversion coefficients of weak transitions were determined measuring electron-gamma coincidences, The half-life of the isomeric level at 649.3 keV has been remeasured to be 27 +/- 3 ns. An extended level scheme is proposed, which is discussed in terms of single-particle excitations and collective quadrupole and octupole vibrations coupled to them, The possible presence of octupole deformation is considered.
