“…QRPA calculations have been extensively used to evaluate the SN neutrino processes in medium-heavy nuclei. SN neutrino interaction rates are evaluated for Mo, Cd and Pb isotopes to be used as SN neutrino detectors [10][11][12][49][50][51]. Electron-capture rates play important roles in SN explosion processes, as discussed recently in [52] and references therein.…”

Gamow-Teller nuclear matrix elements (NMEs) for pairs of β ± ↔ + + 1 0 ground-state-to-ground-state transitions, in particular their geometric mean NME M m , are studied. The observed means M exp m in the medium-heavy mass region are compared with the corresponding single-quasiparticle (qp) NMEs and the means M QRPA m calculated by the proton neutron qp random-phase approximation (pnQRPA). The M m NMEs turn out to be insensitive to the nucleon occupancy/vacancy amplitudes and to the particle-particle interaction parameter g pp of the pnQRPA. The observed mean NMEs are found to be reduced by a coefficient ≈ k 0.23 relative to the effective qp NMEs and by a coefficient ≈ k 0.6 NM with respect to the pnQRPA NMEs. The reductions associated with the spin isospin correlations and nuclear medium effects, and their impact on nuclear double beta decays and astro-neutrino-nuclear interactions are discussed.Keywords: Gamow-Teller beta decay, beta decay matrix element, double beta decay, astro neutrino response, quenching of g A , QRPA nuclear matrix element, astro neutrino nucleosynthesis

“…Finally, a detector with a large mass of 100 Mo can perform real-time spectrometry of low-energy neutrinos from different sources (sun, supernovae, etc.) thanks to the low energy threshold (168 keV) and large cross section for inverse β decay [39].…”

A next-generation neutrinoless double beta decay experiment based on ZnMoO4 scintillating bolometers

et al. 2012

The search for neutrinoless double β decay probes lepton number conservation with high sensitivity and investigates the neutrino nature and mass scale. Experiments presently in preparation will cover the quasi-degeneracy region of the neutrino mass pattern. Probing the inverted hierarchy region requires improved sensitivities and next-generation experiments, based either on large expansions of the present searches or on new ideas. We examine here a novel technology relying on ZnMoO4 scintillating bolometers, which can provide an experiment with background close to zero in the ton × year exposure scale. The promising performance of a pilot detector is presented, both in terms of energy resolution and background control. A preliminary study of the sensitivities of future experiments shows that the inverted hierarchy region is within the reach of the technique here proposed. A realistic phased approach program towards a next-generation search is presented and briefly discussed

“…In the calculations a valence space containing the 3 ω and the 4 ω harmonic oscillator shells plus the 0h 11/2 was used for both protons and neutrons. The particleparticle strength (g pp ) and the particle-hole strength (g ph ) were adjusted for each multipole in order to reproduce the low-lying experimental energy spectrum of the even-even nucleus under consideration [13], [14], [15], [20], [21].…”

In this work we perform calculations of the cross sections for neutral-current neutrino scattering off the 95,97Mo isotopes. Both the incoherent and coherent con- tributions to the cross sections are considered. The wave functions of the initial and final nuclear states are constructed in the context of the quasiparticle phonon model (MQPM). The response of the aformentioned nuclei to supernova neutrinos are computed by folding the obtained cross sections with a two-parameter Fermi-Dirac distribution.
