| Popis: | Two superdeformed bands of 10 transitions each have been found in {sup 189}Tl extending the mass 190 region of superdeformation down to neutron number N=108. The new bands can be interpreted as signature partners and are proposed to be based on a proton i{sub 13/2} ({Omega}=5/2) configuration, in analogy with the yrast superdeformed band structures in the heavier odd-mass Tl isotopes. The dynamic moments of inertia of all these bands show no noticeable differences as function of N, consistent with an essentially constant quadrupole deformation from the center of the island to its edges. {copyright} {ital 1998} {ital The American Physical Society} |
