Abstract
The decay of the entry states in 158Yb populated in the reactions of 149 MeV 20Ne with 144Nd and 146Nd has been investigated with a 4π multidetector system gated by a Ge counter. The average excitation energy, the γ-ray spectra and the angular distributions as a function of multiplicity show several changes in the γ-ray decay. These changes suggest a transition from prolate to particle aligned oblate configuration at low spin. At I ∼ 38-48 collective transitions with dipole and quadrupole component possibly built on high K single particle states are observed. Furthermore, above I ∼ 48 the dipole component disappears suggesting a further change toward more triaxial shape.
