The product of the thermal neutron activation cross section and half-life for manganese-53 is (350 ± 100) x 106 barn-years. If a value of 2 x 106 years is assumed for the half-life of manganese-53, then the cross section is 170 barns. This large cross section affords much greater sensitivity for the determination of manganese-53.
