Abstract
Gamma-ray spectra of neutron-deficient isotopes between cerium () and gadolinium () have been investigated. New bands of states were identified in many even-even, odd-, and odd-odd nuclei. This Letter reports results on the ground-state bands in the even-even nuclei , , , and . The systematic trends of deformation are presented and compared with theoretical predictions. The lightest isotopes appear to be axially symmetric rotors with .
