Abstract

Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the ¹⁵⁵Gd(α,2n)¹⁵⁷Dy and ¹⁴⁸Nd(¹²C,5n)¹⁵⁵Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which are conjectured to be the first candidates of a Kπ=2⁺γ vibrational band, built on the [505]11/2⁻ neutron orbital, in both odd-A155,157Dy isotopes. The coupling of the first excited K=0⁺ states or the so-called β vibrational bands at 661 and 676 keV in ¹⁵⁴Dy and ¹⁵⁶Dy to the [505]11/2− orbital, to produce a Kπ=11/2⁻ band, was not observed in both ¹⁵⁵Dy and ¹⁵⁷Dy, respectively. The implication of these findings on the interpretation of the first excited 0⁺ states in the core nuclei ¹⁵⁴Dy and ¹⁵⁶Dy are also discussed.
