“…It has been observed only in the case of 12 C with accelerator neutrinos [39]. Theoretical work [40] suggests that these cross sections are sensitive to the axial isoscalar component of the weak neutral-current interactions and the strange quark content of the nucleon.…”

The low energy part of the reactor neutrino spectra has not been measured experimentally. Its uncertainties limit the sensitivities in certain reactor neutrino experiments. This article discusses the origin of these uncertainties and examines their effects on the measurements of neutrino interactions with electrons and nuclei. The discrepancies between previous results and the Standard Model expectations can be explained by the under-estimation of the reactor neutrino spectra at low energies. To optimize the experimental sensitivities, measurements forν e -e cross-sections should focus on events with large (>1.5 MeV) recoil energy while those for neutrino magnetic moment searches should emphasize on events <100 keV. The merits and attainable accuracies for neutrino-electron scattering experiments using artificial neutrino sources are discussed.

“…In the experimental side, only a few data measured from accelerated-based ν facilities, which are deduced mainly from 12 C, exist exclusively for the first stage of the two step processes, that is, the formation of compound nuclei. They have been reported as ν flux averaged total cross sections in the last decade [11][12][13][14][15]…”

“…Data for the inclusive reaction, 12 C(ν e , e − ) 12 N * , show about 3.3 ∼ 6.7 in the 10 −42 cm 2 unit including indicated experimental error bars, while data for the exclusive reaction like 12 C(ν e , e − ) 12 N g.s. and 12 C(ν, ν ′ ) 12 C (15.11 MeV) for the DAR neutrino are restricted to 6.07 ∼ 10.4 and 8.5 ∼ 12.3 in the same unit, respectively [11][12][13][14][15].…”

We developed the quasi-particle random phase approximation (QRPA) for the neutrino scattering off even-even nuclei via neutral current (NC) and charged current (CC). The QRPA has been successfully applied for the β and ββ decay of relevant nuclei. To describe neutrino scattering, general multipole transitions by weak interactions with a finite momentum transfer are calculated for NC and CC reaction with detailed formalism. Since we consider neutron-proton (np) pairing as well as neutron-neutron (nn) and proton-proton (pp) pairing correlations, the nn + pp QRPA and np QRPA are combined in a framework, which enables to describe both NC and CC reactions in a consistent way. Numerical results for ν− 12 C, − 56 Fe and − 56 Ni reactions are shown to comply with other theoretical calculations and reproduce well available experimental data.

“…Uncertainties in theoretical calculations are no better than the ∼10-20% level, and unfortunately experimental measurements of neutrino interactions in this energy range are poor or nonexistent. The only measurements with ∼10-20% uncertainties are for 12 C by the Liquid Scintillator Neutrino Detector (LSND) at Los Alamos National Laboratory and KARMEN at Rutherford Appleton Laboratory [72,73]. Future programs to measure cross sections will be highly desirable for an effective interpretation of the next observed supernova burst signal, as well as for the understanding of processes in the supernova itself.…”
