| Popis: | WOS: 000083910700003 Double step resolved gamma-ray transitions linking the yrast superdeformed (SD) band of Gd-149 to the normal deformed (ND) level scheme have been observed using the EUROGAM phase II spectrometer. The excitation energy of the 47/2(-) SD state above the 7/2(-) ground state has thus been determined to be 10.625 MeV. The most likely multipolarity of the Linking transitions is deduced, which permits the assignment of the most probable spins for this SD band. This measurement represents the first observation of discrete gamma-ray transitions linking SD and ND states in the A similar to 150 mass region of the nuclear chart. (C) 1999 Elsevier Science B.V.
