Cs137) p → n + e+ + ν (β+ decay, eg. Na22) The total kinetic energy released in a beta decay, E 0, is the difference in rest energy between theinitial nucleus and the end-products; itis typicallyon the order of 1 MeV. When performing calculations of the beta decay spectrum, you should assume that the recoil kinetic energy of the nucleus is
