Abstract
Lifetimes of states in the two strongest superdeformed (SD) bands in
193Tl were measured using the Doppler-shift attenuation method.
The reaction 176Yb(23Na,6n)193Tl at a beam energy of
129MeV was used and -rays were detected by the Gammasphere
array. Quadrupole moments of 18.3(10) eb and 17.4(10) eb were extracted for
SD bands 1 and 2, respectively, using the fractional Doppler-shifts of the SD
transitions. The previously reported linking transitions of these SD bands
to normal deformed near yrast levels could not be confirmed. No other
candidates for linking transitions could be established.
