WebJan 3, 2024 · All the explanations for why the beta decay of cobalt 60 seem to revolve around 'in a mirror flipped world the process is different', and while I understand the intrinsic relationship between symmetries and conserved quantities I would like to see properly in the maths how the parity eigenvalue is not conserved in this process. WebApr 23, 2024 · Equation 21.4.6 is the same as the equation for the reaction rate of a first-order reaction, except that it uses numbers of atoms instead of concentrations. In fact, radioactive decay is a first-order process and can be described in terms of either the differential rate law ( Equation 21.4.6) or the integrated rate law: (21.4.7) N = N 0 e − k t.

The … WebWhen they show a decay with a certian amount of energy, this energy is net of the masses of the particles. So you get Co = β + Ni + 0.31 MeV, the energy is attached to the ejected beta particle. Fair enough, thanks. So 0.31 MeV is just the kinectic energy of the electron and the anti-neutrino.
