64 Cu is a well-known nuclide that is unstable with respect to both ẞ- and ε / ẞ* decay. (i) Calculate the Q values for these three decay modes. (ii) What are the energies if the neutrino (ẞ* decay) and antineutrino (ẞ- decay) when the charged leptons have kinetic energies ½ the corresponding Q values? (iii) Neglecting the possible excited states of the daughter atom, what is the energy of the neutrino emitted in the ε (electron capture) decay?
