Anegligible amount of this energy goes to the resulting 5726fe atom as kinetic energy. about 90 percent of the time, after the electron-capture process, the 5726fe nucleus emits two successive gamma-ray photons of energies 0.126 mev and 1.40×10−2 mev in decaying to its ground state. the electron-capture process itself emits a massless neutrino, which also carries off kinetic energy. what is the energy of the neutrino emitted in this case?
