NUCLEAR REACTIONS ¹⁸O(n, X), (π⁺, X), (π^-, X), (μ^-, X), (γ, X), [π and γ from interaction of cosmic muons with water], E=high energy; calculated yields of spallation products from interaction of cosmic-ray muons with water, and resultant background from β decays of spallation products of ⁸He, ^8,9,11Li, ^8,12,13,14B, ^9,15,16C, ^11,12Be, ^12,16,17,18N, ¹³O, and that by stable isotopes of ^9,10Be, ^10,11B, ^{10,11,12,13,14}C, ^13,14,15N, ^14,15O; calculated simulated cosmic-ray muon flux spectrum, energy loss for vertical through-going muons passing through Super-Kamiokande (Super-K) fiducial volume, secondary particle path length spectra and absorption distance produced by cosmic-ray muons in Super-K, spallation decay rate distribution and background energy spectra, parent particle kinetic energy spectra, cumulative distribution of isotopes perpendicular to the muon track. Relevance to backgrounds for experiments concerned with detection of solar neutrinos or diffuse supernova neutrino background (DSNB) signals as in Super-Kamiokande project. Used simulation code FLUKA and other theoretical insights. Comparison with available experimental data from Super-Kamiokande.
