β⁺-delayed spectroscopy of neutron-rich tantalum nuclei: Shape evolution in neutron-rich tungsten isotopes

NUCLEAR REACTIONS Be(²⁰⁸Pb, X)¹⁸⁶Hf/¹⁸⁷Hf/¹⁸⁸Hf/¹⁸⁹Hf/¹⁸⁸Ta/¹⁸⁹Ta/¹⁹⁰Ta/¹⁹¹Ta/¹⁹²Ta/¹⁹⁰W/¹⁹¹W/¹⁹²W/¹⁹³W/¹⁹⁴W/¹⁹²Re/¹⁹³Re/¹⁹⁴Re/¹⁹⁵Re/¹⁹⁶Re, E=1 GeV/nucleon; measured yields. ¹⁸⁷Hf, ^188,189,190Ta, ^190,191W, ^192,193Re; measured delayed γ; deduced isomers and half-lives.

RADIOACTIVITY ^188,190,192Ta(β^-)[from Be(²⁰⁸Pb, X), E=1 GeV/nucleon]; measured Eγ, Iγ, γγ-coin, βγ correlations, and half-lives using GSI Fragment separator, MUSIC ionization chamber; and RISING array. ^188,190,192W; deduced levels, J, π, logft. Comparison with interacting boson approximation (IBA-1) calculations for ¹⁹⁰W. Z=56-80, N=84-122; discussed systematics of first 2+ and 4+ states, B(E2), and γ deformation parameter in even-even nuclei.
