Searching signature of neutrino-nucleus coherent scattering with Mössbauer Spectroscopy

Abstract

The Mössbauer spectroscopy is presented as an alternative experimental technique to be pursued in the detection of Coherent Elastic ν-Nucleus Scattering (CENNS). The neutrino transferred energy in the neutrino-nucleus interaction causes a perturbation at the nuclear levels which are responsible for gamma radiation in Mössbauer resonance. The main characteristic of Mössbauer spectroscopy is the recoil less condition imposed on the nuclei imposed by quantum restrictions of the crystalline array potential. Coherent neutrino scattering is expected to occurs low energy regime of the beam, typically below 30 MeV, at higher neutrino energies small incoherence component appears in the scattering[30] as disturbances within the internal nuclear degrees of freedom. In this work we have shown that using anti neutrino reactor beam, with the accuracy of Mössbauer technique its possible to obtain a measurable signature of the Coherent neutrino Scattering.
