Atomic-binding effects in inelastic ν e scattering
Dobrotsvetov A. B., Fayans S. A., Dobretsov V. Yu.
The energy spectra of the electrons knocked out of various atomic shells in the course of ve scattering are calculated in the minimal electroweak model. The electromagnetic form factors of the neutrino are taken into account. These spectra are found to be quite different from those in the case of free scattering. These differences are found not only when the energies of the impinging neutrinos are comparable to the binding energy of the electron but also at energies an order of magnitude greater. For a scattering due to the magnetic moment, the cross section for bound electrons is always smaller than that for free electrons. The spectrum of recoil electrons does not diverge at small kinetic energies. It cuts off in a natural way and has a plateau. The role played by these effects in the scattering of fission-reactor ve's is examined.
