Abstract: Lifetimes of states in the two strongest superdeformed (SD) bands in <superscript>193</superscript>Tl were measured using the Doppler-shift attenuation method. The reaction <superscript>176</superscript>Yb(<superscript>23</superscript>Na,6n)<superscript>193</superscript>Tl at a beam energy of 129 MeV was used and γ-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.
