Br$sup 86$--A NEW NUCLIDE
The nuclide Br/sup 86/ has been identified by chemical separation following neutron bombardment of enriched Kr/sup 86/. A half-life of 54 plus or minus 2 sec was observed. BETA - and gamma -scintillation counting with multichannel pulse-height analysis indicate a complex beta spectrum with an end point of 7.1 plus or minus 0.5 Mev for the most energetic component and prominent gamma rays st 1.57 and 2.76 Mev. The effect of Br/sup 86/ on the interpretation of previous data on short-lived bromine fission products is discussed. Rough values for the relative (n,p), (n,pn), and (n, alpha ) reactions on Kr/sup 86/ were determined as 1: 1: 0.05, respectively. The ratio of Se/sup 83/ isomers formed by the (n, alpha ) reaction is 3: 1 in favor of the metastable state. (auth)
