- Determination of the effective cross section of the reaction 81Br(n,p)81Sem for fission neutrons. Pfrepper, G.; Raitchev, Kh.; Mikhailov, M. (Zentralinst. Isot.- Strahlenforsch., DAW, Leipzig, E. Ger.). Radiochim. Acta, 23(1), 55-6 (German) 1976. CODEN: RAACAP. DOCUMENT TYPE: Journal CA Section: 70 (Nuclear Phenomena) A radiochem. sepn. method was used to isolate the 81Sem [15422-58-9] activity (esp. to sep. the considerable activities of 80Brm, 80Br, 82Brm, and 82Bbr, after n irradn. (6 .times. 1012 n/s-cm2) for 2 h of NH4Br together with SeO2 as a std. In the sample sepd. from the NH4Br, 81Sem (103 keV) and 81Se (276, 290 keV) were detectable by .gamma.-spectrometry. The Cd-ratio for the reaction 81Br(n,p)81Sem was found to be .hivin.RCd = 1.
