When negatively charged particles are scattered by atomic nuclei before the thresholds of excitation nuclei, formation a metastable system "charged particle + excited nucleus" is possible. In particular, during scattering μ-mesons mesoatoms with an nucleus in states entire spectrum hydrogen-like atoms can arise. This infinite set quasi-bound generates series elastic resonances continuous spectr...

The next generation of long-baseline neutrino experiments will be capable precision measurements oscillation parameters, neutrino-nucleus scattering, and unprecedented sensitivity to physics beyond the Standard Model. Reduced uncertainties in fluxes are necessary achieve high these future precise measurements. New hadron-nucleus interaction cross sections needed reduce fluxes. We report differe...
