Lifetime measurements probing triple shape coexistence in ¹⁷⁵Au

NUCLEAR REACTIONS ⁹²Mo(⁸⁶Sr, 2np), E=401 MeV; measured Eγ, Iγ, αγ-, (evaporation residues)αγ-coin, half-lives by recoil-distance Doppler-shift (RDDS) and differential decay curve methods using Cologne plunger device and JUROGAM array. Recoil-decay tagging method using Gamma Recoil Electron Alpha Tagging (GREAT) spectrometer. ¹⁷⁵Au; deduced level, J, π, B(E2), B(E1), transition quadrupole moment. Systematics of transition quadrupole moments in ¹⁷⁵Au, ¹⁷⁸Pt, ^180,182Hg, ¹⁸⁶Pb, ¹⁸⁷Tl. Spherical, prolate, and mixed oblate-prolate configurations.

RADIOACTIVITY ^175mAu(α); measured Eα, half-life of 11/2- isomer by correlations between recoil implantations and α decays.
