Half-life of the yrast 2⁺ state in ¹⁸⁸W: Evolution of deformation and collectivity in neutron-rich tungsten isotopes

NUCLEAR REACTIONS ¹⁸⁶W(⁷Li, pα), E=35 MeV; measured Eγ, γγ-coin, T_1/2 of first 2+ state by γγ(t) at IFIN-HH, Bucharest facility. ¹⁸⁸W; deduced level, B(E2) for first 2+ state, enhanced γ softness in ¹⁸⁸W. Systematics of energies of low-lying 0+, 2+ and 4+ states and B(E2) values for first 2+ states in even-even Hf, W, Os and Pt nuclei with N=102-120.

NUCLEAR STRUCTURE ^{184,186,188,190,192,194}W; calculated Woods-Saxon potential energy surface (PES) contours in (β, γ) plane; deduced prolate to oblate shape transition.
