Yrare low-spin positive-parity states in N = 88 ₆₆¹⁵⁴Dy

NUCLEAR REACTIONS ¹⁵⁵Gd(³He, 4n), E=37.5 MeV; measured Eγ, Iγ(θ_), γγ-coin, DCO ratios, polarization asymmetries using AFRODITE spectrometer array (9 HPGe clover detectors in BGO shields). ¹⁵⁴Dy; deduced levels, J, π, γ-transitions, γ band, K^π=2⁺ band, staggering parameter, γ-transitions multipolarity, kinematical moment of inertia vs rotational frequency for yrast band and for non-yrast positive-parity bands, rotational bands states energy relative to liquid-drop reference of the low spin bands. ¹⁵⁰Sm, ¹⁵²Gd, ¹⁵⁴Dy, ¹⁵⁶Er, ¹⁵⁸Yb; deduced staggering parameters vs spin.
