Abstract

Theβ- andγ-radiation of Ir192 and Ir194, produced by slow neutron irradiation, has been studied with scintillation spectrometers. A new isomeric activity with a (47±2) second-half life is found to be Ir194m, decaying by a 130 kev-transition to Ir194 and byβ-emission to excited states of Pt194. Gamma rays of energy (130±4), (323±7) and (625±20) kev were found. An upper limit for the conversion coefficient of the isomeric transition is given, which shows in connection with energy-half life-relations, that the 130 kev gamma ray is anE 3 transition.
