“…The reliability of our present results, furthermore, is justified as follows: (1) from the comparison of the present original cross sections with similar calculations carried out by using (i) CRPA [52,[61][62][63][64] and (ii) QRPA [6,7,37,38,56,65,68] (In these studies the cross sections obtained refer to isotopes such as 56 Fe [52], 208 Pb [63], 128,130 Te [6], the stable even-even Mo isotopes [37,38], and others [19,21]) and (2) from the comparison of the subsequently obtained convoluted QRPA cross sections with previous flux-averaged cross sections (see discussion in Sec. III C below).…”

“…The quantities σ incoh tot and σ coh can be readily computed for SN neutrinos and, due to the fact that the coherent channel dominates over the incoherent one, for neutral current ν-nucleus scattering it holds σ coh σ incoh tot (see Ref. [37][38][39]). …”

“…On the other hand, theoretically the nuclear responses of the ν detector to the energy spectra of the observed neutrino flux could be simulated by convoluted (folded) cross sections obtained by using realistic description for the ν beam of the studied neutrino source [26,[31][32][33]. In the case of the supernova (SN) neutrinos we address in this work, however, despite the fact that the actual neutrino-nucleus cross sections play a crucial role in unraveling the various SN explosion scenarios [5,20] and also in constraining the parameters of the relevant nuclear structure theory [6][7][8][34][35][36][37][38][39], cross section measurements are not available for many nuclear reactions occurring in a SN [3,5].…”

“…As is well known, in the case of the NC ν-nucleus scattering the coherent channel (gs → gs transitions) is also possible [37,38]. However, in terrestrial experiments the detection of this channel may be achieved through a measurement of the nuclear recoil signal [43][44][45] that provides a signature different than that of the incoherent channel [1,3,6,7].…”

Nuclear responses to energy spectra of supernova (SN) neutrinos are studied by folding original ν-nucleus cross sections calculated in the context of the quasiparticle random-phase approximation using realistic two-body forces. To this purpose, we employ two-parameter neutrino-energy distributions of Fermi-Dirac and power-law shapes for various SN neutrino scenarios. As concrete examples of promising neutrino detectors we have chosen the 64,66 Zn isotopes, contents of (i) the semiconductor CdZnTe (COBRA experiment) and (ii) the crystal scintillators ZnMoO 4 and ZnWO 4 . These materials are quite advantageous for measuring double-β-decay events and for potential use in studying current neutrino physics issues. We concentrate on the evaluation of folded differential cross sections, [dσ (ω)/dω] fold , and flux-averaged cumulative cross sections, [dσ (ω)/dω] cum fold , as well as total cross sections, σ tot , of the above Zn isotopes by adopting several realistic SN neutrino models parametrized by the neutrino temperature or the mean neutrino energy and the width of the aforementioned distributions.

“…The latter are provided through the application of the three point formulas (see Appendix) by using the empirical separation energies (for protons and neutrons, S p,n ) of the neighbouring nuclear isotopes [13,32]. The values of the g p,n pair adjust reliably the empirical energy gaps (see Table I) [11,13,32,69,70].…”

Neutrino-nucleus reactions cross sections, obtained for neutrino energies in the range εν ≤ 100 − 120 MeV (low-and intermediate-energy range), which refer to promising neutrino detection targets of current terrestrial neutrino experiments, are presented and discussed. At first, we evaluated original cross sections for elastic scattering of neutrinos produced from various astrophysical and laboratory neutrino sources with the most abundant Cd isotopes 112 Cd, 114 Cd and 116 Cd. These isotopes constitute the main material of the COBRA detector aiming to search for neutrinoless double beta decay events and neutrino-nucleus scattering events at the Gran Sasso laboratory (LNGS). The coherent ν-nucleus reaction channel addressed with emphasis here, dominates the neutral current ν-nucleus scattering, events of which have only recently been observed for a first time in the COHERENT experiment at Oak Ridge. Subsequently, simulated ν-signals expected to be recorded at Cd detectors are derived through the application of modern simulation techniques and employment of reliable neutrino distributions of astrophysical ν-sources (as the solar, supernova and Earth neutrinos), as well as laboratory neutrinos (like the reactor neutrinos, the neutrinos produced from pion-muon decay at rest and the β-beam neutrinos produced from the acceleration of radioactive isotopes at storage rings as e.g. at CERN).
