Octupole correlations in N = 88 ¹⁵⁴Dy: Octupole vibration versus stable deformation

NUCLEAR REACTIONS ¹⁵⁵Gd(³He, 4n), E=37.5 MeV; measured Eγ, Iγ, γγ-coin using AFRODITE array at the Cyclotron facility of the iThemba Laboratory. ¹⁵⁴Dy; deduced levels, J, π, bands, B(E1)/B(E2) ratios, E1 transitions, level energy differences between the positive- and negative-parity bands, octupole deformation. Comparison with level-energy differences and B(E1)/B(E2) ratios in ¹⁵⁰Sm, ¹⁵²Gd, ²²⁴Ra.
