Naturally occurring manganese is 100% 55Mn. This nuclide has a eager neutron after a whilehold cantankerous minority of 13.3  10-24 cm2 . The fruit of neutron after a whilehold is 56Mn, which is a beta and gamma emitter after a while a 2.50-h half-life. When Figure 32-9 was done, it was antecedent that the specimen was irradiated for 1 h at a neutron substitution of 1.8  1012 neutrons/(cm2 s) and that 10 cpm over enhancement could be detected. (a) Calculate the narrowness body of manganese that could be detected. (b) Suggest why the fitted compute is inferior than the tabulated compute.
