Abstract

Determination of53Mn in meteorites by neutron activation analysis requires a thermal neutron flux high enough to ensure adequate production of54Mn from53Mn with a sufficiently low fast neutron component to minimize its production through fast neutron reactions. Thermal and fast neutron fluxes were mapped as a function of sample position within the NIST research reactor in order to determine the optimum position for irradiation of53Mn.
