Abstract
The decay of the entry states in /sup 158/Yb populated in the reactions of 149 MeV /sup 20/Ne with /sup 144/Nd and /sup 146/Nd has been investigated with a 4 ..pi.. multidetector system gated by a Ge counter. The average exitation energy, the ..gamma..-ray spectra and the angular distributions as a function of multiplicity show several changes in the ..gamma..-ray decay. These changes suggest a transition from prolate to particle aligned oblate configuration at I approx. 28. At I 38 to 48 collective transitions with dipole and quadrupole component are observed. Possible explanations for these transitions are discussed in terms of nuclear shapes. Furthermore, above I approx. 48 the dipole component disappears suggesting a further change toward more triaxial shape. 19 references.
