| Abstract: | The half-lives of several short-lived noble-gas and halogen nuclides produced in fission have been determined via their long-lived decay products using a gas-flow method. The following half-lives have been obtained: 91Br 0·63±0·07 sec, 95Kr 0·78±0·03 sec, 140I 0·86±0·04 sec, 141I 0·42±0·08 sec and 144Xe 1·15 ±0·20 sec. |
