Background: In the environment of high neutrino-fluxes provided incore-collapse supernovae or neutron star mergers, neutrino-induced reactionswith nuclei contribute to the nucleosynthesis processes. A number ofterrestrial neutrino detectors are based on inelastic neutrino-nucleusscattering and modeling of the respective cross sections allow predictions ofthe expected detector reaction rates.  Purpose: To provide a self-consistent microscopic description ofneutrino-nucleus cross sections involving a large pool of Z = 8 - 82 nuclei forthe implementation in models of nucleosynthesis and neutrino detectorsimulations.  Methods: Self-consistent theory framework based on relativistic nuclearenergy density functional is employed to determine the nuclear structure of theinitial state and relevant transitions to excited states induced by neutrinos.The weak neutrino-nucleus interaction is employed in the current-current formand a complete set of transition operators is taken into account.  Results: We perform large-scale calculations of charged-currentneutrino-nucleus cross sections, including those averaged over supernovaneutrino fluxes, for the set of even-even target nuclei from oxygen toward lead(Z = 8 - 82), spanning N = 8 - 182 (OPb pool). The model calculations includeallowed and forbidden transitions up to J = 5 multipoles.  Conclusions: The present analysis shows that the self-consistent calculationsresult in considerable differences in comparison to previously reported crosssections, and for a large number of target nuclei the cross sections areenhanced. Revision in modeling r-process nucleosynthesis based on aself-consistent description of neutrino-induced reactions would allow anupdated insight into the origin of elements in the Universe and it wouldprovide the estimate of uncertainties in the calculated element abundancepatterns.
