The nuclear cross-section of the reaction 81Br (n,) Br82 has been measured by irradiation of Barium Bromide (BaBr2) in a thermal neutron flux of 4.2 x 1013 n cm-2 s-1. The BaBr2 was chemically processed and measured as Hydrogen Bromide (HBr82). The value of nuclear cross-section was determined to be 2.1 0.2 barns, which falls within the range of values as previously reported elsewhere.
