DELAYED COINCIDENCE MEASUREMENT OF THE LIFETIME OF THE 129-kev LEVEL IN Ir 191
The lifetime of the 129-kev level in Ir/sup 191/ was measured by the delayed coincidence technique. The half-life was found to be (13.1 plus or minus 1.0) x 10-/sup 11/ seconds. This value is compared with the.result of the measurements of the level width by Mossbauer experiments. The properties of the two first excited states in Ir/sup 191/ and Ir/sup 193/ are discussed.
