“…The cross sections to excite 3/2 − 1 states in 13 C and 13 N induced by GT transitions are found to be enhanced compared to those obtained by the Cohen-Kurath interaction as shwon in figure 2 [20]. Calculated cross sections for solar 8 B neutrinos are compared in table 1.…”

Abstract. Remarkable improvements in the evaluation of neutrino-nucleus reaction cross sections are obtained based on new shell-model Hamiltonians with proper tensor components. New ν-induced reaction cross sections on 12 C, 13 C, 56 Fe, 56 Ni and 40 Ar are presented, and predictions for nucleosynthesis in supernova explosions, ν-oscillation effects and low-energy reactor and solar neutrino detection are discussed based on these new cross sections.

LENA (Low Energy Neutrino Astronomy) has been proposed as a next generation 50 kt liquid scintillator detector. The large target mass allows a high precision measurement of the solar 8 B neutrino spectrum, with an unprecedented energy threshold of 2 MeV. Hence, it can probe the MSW-LMA prediction for the electron neutrino survival probability in the transition region between vacuum and matter-dominated neutrino oscillations. Based on Monte Carlo simulations of the solar neutrino and the corresponding background spectra, it was found that the predicted upturn of the solar 8 B neutrino spectrum can be detected with 5σ significance after 5 years.

“…In this Letter, we show that organic liquid scintillator detectors can also measure the 8 B solar neutrino flux by means of the ν e charged current interaction with the 13 C nuclei naturally contained in the scintillators. The possibility to use 13 C as a target for 8 B neutrinos was pointed out in the past by [14,15,16]. Here, we propose a technique to tag the solar neutrino events.…”

“…Here, only the excited state 13 C * (3.68MeV) is relevant and the excitation to other levels has negligible cross section. The cross section for this process, averaged over the 8 B neutrino spectrum, is σ NC = 1.15 × 10 −43 cm 2 [14,16] and it is affected by about 30 − 40% uncertainty. The process is in principle very interesting since it can give a measure of the total 8 B flux and can be also tagged by a monochromatic γ-ray emission back to the ground state.…”

How to observe 8B solar neutrinos in liquid scintillator detectors

We show that liquid organic scintillator detectors (e.g., KamLAND and Borexino) can measure the 8B solar neutrino flux by means of the nu_e charged current interaction with the 13C nuclei naturally contained in the scintillators. The neutrino events can be identified by exploiting the time and space coincidence with the subsequent decay of the produced 13N nuclei. We perform a detailed analysis of the background in KamLAND, Borexino and in a possible liquid scintillator detector at SNOLab, showing that the 8B solar neutrino signal can be extracted with a reasonable uncertainty in a few years of data taking. KamLAND should be able to extract about 18 solar neutrino events from the already collected data. Prospects for gigantic scintillator detectors (such as LENA) are also studied.Comment: 15 pages, 1 figure. Very few changes in the text. Final version to be published on Phys. Lett.
