THE DECAY OF Ir$sup 19$$sup 4$
The decay of Ir/sup 194/ was investigated by means of a double focusing spectrometer, mostly by the photo-electron technique. A total of 32 transitions was observed, and their energies and intensities were measured. An internally converted transition of 1480 kev, for which no gamma ray could be detected, showed that a 0+ state of this energy is populated. The log ft values for the beta branches showed that all the l8 levels excited are of even parity. By comparison of the measured gamma intensities with the conversion intensities of corresponding transitions in the decay of Au/sup 194/, spin values could be assigned for many levels. Evidence for a new 0+ state at 1547 kev was obtained in this manner. Indications were found for EO admixture in competition with Ml and E2 multipolarities. A state of 923 kev may be interpreted as the 3+ level in the asymmetric rotor theory. (auth)
