摘要：

High-spin states in 149Gd have been investigated via the Sn-124(Si-30, 5n)149Gd reaction at a beam energy of 150 MeV. Measurements of gamma-gamma-coincidences and angular distributions with respect to the nuclear spin axis allowed the decay scheme to be extended up to J congruent-to 85/2HBAR and E* congruent-to 16 MeV. Single-particle configurations were assigned to many high-spin levels based on calculations performed with the deformed Woods-Saxon potential.
