Quadrupole moments of coexisting collective shapes at high spin in ¹⁵⁴Er

NUCLEAR REACTIONS ¹¹⁰Pd(⁴⁸Ti, 4n), E=215 MeV; measured Eγ, Iγ, γγ-coin, fractional Doppler-shift values F(τ) vs Eγ. ¹⁵⁴Er; deduced high-spin levels, triaxial strongly deformed (TSD), and superdeformed (SD) bands, transition quadrupole moments, configurations. Configuration-dependent cranked Nilsson-Strutinsky (CNS) calculations. Total energy surface calculations. Systematics of dynamic moment of inertia plots for bands in N=86 isotones ¹⁵²Dy, ¹⁵³Ho and ¹⁵⁴Er.
