Abstract

The neutron capture cross section of Sr⁸⁹ has been measured by an activation method. Naturally occurring strontium was irradiated in different high flux positions in the NRX reactor at Chalk River and the amount of Sr⁹⁰ formed by successive neutron capture in Sr⁸⁸ was determined by separating and measuring its daughter Y⁹⁰. Using values of 36.6 and 0.005 barns for the respective neutron capture cross sections of Co⁵⁹ and Sr⁸⁸, the capture cross section of Sr⁸⁹ for reactor spectrum neutrons was found to be 0.49 ± 0.10 barn.
