Neutral-current neutrino cross section and expected supernova signals for 40Ar from a three-fold increase in the magnetic dipole strength
In view of the great interest in liquid argon neutrino detectors, the 40Ar(γ,γ′)40Ar reaction was revisited to guide a calculation of the neutral current neutrino cross section at supernova energies. Using the nuclear resonance fluorescence technique with a monoenergetic, 99% linearly polarized phot...

| Summary: | In view of the great interest in liquid argon neutrino detectors, the 40Ar(γ,γ′)40Ar reaction was revisited to guide a calculation of the neutral current neutrino cross section at supernova energies. Using the nuclear resonance fluorescence technique with a monoenergetic, 99% linearly polarized photon beam, we report a three-fold increase in magnetic dipole strength at around 10 MeV in 40Ar. Based on shell-model calculations, and using the experimentally identified transitions, the neutral current neutrino cross sections for low-energy reactions on 40Ar are calculated. |
