Abstract

A superdeformed rotational structure is reported in the stable nucleus ⁶⁸ Zn. It has a transition quadrupole moment (Q_t) of 2.5 ^{+ 0.7}_{− 0.4} e b (β ≈ 0.4), as measured by the residual Doppler shift method. Theoretical calculations suggest that two different configurations are possible candidates for this band. One is built without h_11/2 neutrons, as seen in superdeformed bands in the A ˜ 60 region, while the other involves one h_11/12 neutron in analogy with superdeformed bands in the A ˜ 80 region. The second of these candidate configurations is preferred, thus establishing a new, neutron-rich (relative to the line of β stability) region of superdeformation with Z ˜ 30 and N ˜ 38.
