Abstract: | An in-beam γ-ray study with the144Sm (α, p4n) reaction has established the high-spin states up to 5 MeV excitation and I=35/2 in the N=80 nucleus143Eu. The observed yrast states show the typical irregular pattern of a spherical nucleus, with frequent decay branchings and often dominant dipole de-excitation. The level spectrum is in qualitative accord with the coupling of the h11/2 proton particle to the known yrast levels of the142Sm core nucleus. Only in a few cases specific configuration assignments are made. |
