SUPERDEFORMED BAND IN CE-130

An ''identical'' superdeformed (SD) band has been discovered in the nu cleus Ce-130. This band has transition energies which are identical to the half-way points between the energies in the yrast SD band of Ce-1 31 to a mean degeneracy of 0.4%. The discovery of this band completes the chain of SD Ce isotopes from Ce-129 to Ce-133. However, at 0.5% of the reaction channel, it is populated with an intensity which is an o rder of magnitude smaller than neighboring SD bands. The valence neutr on configuration is assigned as v6(1) with a hole in either the [523]7 /2(-) or [411]1/2(+) Nilsson orbitals.
