Abstract

Low-spin states of Dy157 have been studied using the JUROGAM II array, following the Gd155 (α, 2n) reaction at a beam energy of 25 MeV. The level scheme of Dy157 has been expanded with four new bands. Rotational structures built on the [523]5/2- and [402]3/2+ neutron orbitals constitute new additions to the level scheme as do many of the inter- and intraband transitions. This manuscript also reports the observation of cross I+→(I-1)- and I-→(I-1)+ E1 dipole transitions interlinking structures built on the [523]5/2- (band 5) and [402]3/2+ (band 7) neutron orbitals. These interlacing band structures are interpreted as the bands of parity doublets with simplex quantum number s=-i related to possible octupole correlations.
