Identification of a 66 μs isomeric state in ¹⁷⁵Ir

RADIOACTIVITY ¹⁷⁵Ir(IT)[from ⁹²Mo(⁸⁸Sr, αp), E=381 MeV, followed by separation of fragments using RITU separator at the University of Jyvaskyla K130 cyclotron facility]; measured Eγ, Iγ, γγ-coin, and isomer half-life by isomer tagging technique using the JUROGAM-II array. ¹⁷⁵Ir; deduced levels, J, π, isomer, total conversion coefficients, multipolarities, B(E1), B(M1). Comparison with the decay of a 326-ns, 3/2- isomer in ¹⁷⁹Au.
