Abstract
Gamma ray spectra of a mixture of the isotopes86Br and87Br have been measured by means of a Ge(Li) detector. Both manual and automated techniques were used to separate bromine from other fission products of natural uranium.
A total of 13 gamma rays were observed. The most intense of the86Br gamma peaks (1,565 keV) was found to grow in with a half-life of 4.5±1 s. This is explained to be due to an isomeric state in86Br decaying to the ground state.
