✦ Synopsis

Superdeformation studies in lsg '191'192T1 at Gammasphere are discussed. New results on 191T1 are the observation of interband transitions between the signature partner E2 bands and the measurement of an average quadrupole moment (Q0 = 18 4-1 eb) for these superdeformed structures. These data enable us to derive absolute M1 strengths and confirm that the 81 ~t proton occupies the [642]5/2 orbital. Tentative data for one superdeformed sequence in ISOTI are consistent with the prediction of a decrease in quadrupole deformation for the lightest nuclei at the limit of this island of superdeformation.
