Description
Long-lived isomeric states in 190Ir have been investigated with the 192Os(p,3n)190Ir and192Os(d,4n)190Ir reactions using beams of 18-31 MeV protons and 27.8 MeV deuterons, respectively. A series of measurements, including excitation functions, half lives, e-γ coincidences and e-e-coincidences, was performed. Five new transitions were observed, and the results of e-γ and e-e- coincidences indicate that these transitions are fed by the 148.7 keV M4 transition that depopulates the 11- isomer. The previous decay scheme is shown to be incorrect, and the results allow the ground state parity and mass excess to be determined. (orig.)
