Question

Draw energy spectrum of beta decay followed by gama decay in 27co^60

Answer 1

Co precursor. The simplest case of the latter would result from the activation of 58. Fe . 60. Co decaysby beta decay to the stable isotope nickel-60 (60. Ni ). The activated nickel nucleus emits two gammarays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is 59 27Co+ n → 60 27Co
