The decay of 195Ir and 195mIr

Excited states in195Pt from the decay of 2.3h195Irg, 3.7h195Ir m and 183d195Au

“…Analysis of the decay data of the gamma rays of 173, 365 and 433 keV resulted in a half-life of 3.67_+0.08 h for the higher ~gSIr isomer (Fig. 2) in agreement with the value 4.0 + 0.15 h of Hofstetter and Daly [5]. No strong gamma ray decays merely with the half-life for the ground state, for which a value 2.8-t-0.1 h was reported [5].…”

“…2) in agreement with the value 4.0 + 0.15 h of Hofstetter and Daly [5]. No strong gamma ray decays merely with the half-life for the ground state, for which a value 2.8-t-0.1 h was reported [5]. Our earlier [10] estimate of 2.3_+0,2 h results from the analysis of the decay curves for the 99 and 130 keV gamma rays (Fig.…”

“…Earlier attempts to study this decay have not been very successful (see Ref. [5], Introduction). The values reported for the half-life and the beta-and gamma-ray energies of this isotope [6][7][8][9] do not agree and no decay scheme has been given yet.…”

“…The values reported for the half-life and the beta-and gamma-ray energies of this isotope [6][7][8][9] do not agree and no decay scheme has been given yet. In a study with Ge(Li) detectors Hofstetter and Daly [5] showed the existence of two isomers of 19Sir with half-lives of 2.8_+0.1 h and 4.0_+0.15 h, interpreted as the ground state and an excited isomeric state respectively. Twenty gamma rays were reported but no decay scheme was proposed.…”
