Abstract

The EUROGAM Phase 2 array has been used to detect γ rays following the reaction of 30Si on 58Ni at 134 MeV. Two rotational cascades exhibiting characteristic superdeformed behaviour have been observed in 82Sr. Cranked Woods-Saxon calculations have been performed and these suggest that both bands have the ν52π51 intrinsic intruder configuration and that they differ in the signature component of the [431]12 proton orbital which is occupied.
