Evolution of structure and shapes in ¹⁵⁸Er to ultrahigh spin

NUCLEAR REACTIONS ¹¹⁴Cd(⁴⁸Ca, 4n)¹⁵⁸Er, E=215 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ). ¹⁵⁸Er; deduced levels, J, π, high-spin states, angular intensity ratios, δ, B(M1/E2) ratios, nuclear shapes, alignments, rotational bands, configurations, band terminating states and feeding, transition quadrupole moments for triaxial strongly deformed bands, moment of inertia. Comparison with cranked Nilsson-Strutinski calculations. Systematics of triaxial strongly deformed bands in ¹⁵⁸Er, ¹⁶⁰Er, ¹⁵²Dy, ¹⁶³Lu.
