Shapes, softness, and nonyrast collectivity in ¹⁸⁶W

NUCLEAR REACTIONS ¹⁸⁶W(¹³⁶Xe, ¹³⁶Xe')¹⁸⁶W, E=725, 800 MeV from ATLAS-ANL facility; measured scattered beam- and target-like ions using Rochester-Livermore 4π CHICO2 array, Eγ, Iγ, γγ- and (particle)γ-coin, gγ(θ)(DCO) using Gammasphere array. ¹⁸⁶W; deduced high-spin levels, J, π, Kπ, multipolarities, rotational bands, odd-even staggering parameters S(J) for bands and compared with predictions for an axially symmetric rotor, a rigid asymmetric rotor and a γ-unstable nucleus, B(E1) ratios. Systematics of E(first 2+), E(first 4+)/E(first 2+), E(second 2+)/E(first 2+), E(second 0+)/E(first 2+) for A=178-188 even-A W isotopes, and staggering parameters for ^{178,180,182,184,186,188}W, ^178,180Hf, ¹⁸⁸Os.
