A hybrid shell-model/quasiparticle-phonon calculation predicts that inelastic neutrino scattering off 203/205Tl is several times larger at high neutrino energies than earlier shell-model-only estimates, and can rival coherent scattering for diffuse supernova neutrinos.

abstract
The physics reach of a low threshold (100 eV) scintillating argon bubble chamber sensitive to Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS) from reactor neutrinos is studied. The sensitivity to the weak mixing angle, neutrino magnetic moment, and a light $Z'$ gauge boson mediator are analyzed. A Monte Carlo simulation of the backgrounds is performed to assess their contribution to the signal. The analysis shows that world-leading sensitivities are achieved with a one-year exposure for a 10 kg chamber at 3 m from a 1 MW$_{th}$ research reactor or a 100 kg chamber at 30 m from a 2000 MW$_{th}$ power reactor. Such a detector has the potential to become the leading technology to study CE$\nu$NS using nuclear reactors.

Inelastic neutrino-nucleus scattering off $^{203/205}$Tl in terms of the nuclear recoil energy using a hybrid nuclear model
A hybrid shell-model/quasiparticle-phonon calculation predicts that inelastic neutrino scattering off 203/205Tl is several times larger at high neutrino energies than earlier shell-model-only estimates, and can rival coherent scattering for diffuse supernova neutrinos.
