New insight into the shape coexistence and shape evolution of ¹⁵⁷Yb

NUCLEAR REACTIONS ¹⁴⁴Sm(¹⁶O, 3n), E=85 MeV; measured Eγ, Iγ, γγ-coin, DCO ratios, ¹⁵⁷Yb; deduced levels, J, π, high-spin structures, alignments, rotational bands, configurations. Comparisons with total Routhian surface (TRS) calculations and evidence of prolate, triaxial, and oblate shapes. Systematics of low-lying levels in N=87 isotones: ¹⁵¹Gd, ¹⁵³Dy, ¹⁵⁵Er, ¹⁵⁷Yb and ¹⁵⁹Hf.
