Abstract: | The 158Gd(α, 2n)160Dy reaction has been used to study rotational side bands in 160Dy. Several negative-parity bands are observed, with several members of Kπ = 1−, 2− and 4− bands and of a Kπ = 8− band only the bandhead. A pronounced odd-even staggering of moments of inertia is found for members of the Kπ = 2− band. Of the positive-parity bands the Kπ = 2+ (γ) band, which is seen up to a possible spin of 12 and low-spin members of Kπ = (0+), (S), and 4+ bands are observed. The mixing between most of the γ-band and S-band members is observed to be smaller than 2% and no evidence for possible anti-alignment of low-spin S-band members with rotation is found. |
