In the previous paper (Part1), we have verified that the SK assumption on thedirection does not hold in the analysis of neutrino events occurred inside theSK detector, which is the cornerstone for their analysis of zenith angledistributions of neutrino events. Based on the correlation between L_nu andL_mu (Figures~16 to 18 in Part1) and the correlation between E_nu and E_mu(Figure19 in Part1), we have made four possible L/E analyses, namely L_nu/E_nu,L_nu/E_mu, L_mu/E_mu and L_mu/E_nu. Among four kinds of L/E analyses, we haveshown that only L_nu/E_nu analysis can give the signature of maximumoscillations clearly, not only the first maximum oscillation but also thesecond and third maximum oscillation and etc., as they should be, while theL_mu/E_mu analysis which are really done by Super-Kamiokande Collaborationcannot give any maximum oscillation at all. It is thus concluded from thoseresults that the experiments with the use of the cosmic-ray beam for neutrinooscillation, such as Super-Kamiokande type experiment, are unable to lead themaximum oscillation from their L/E analysis, because the incident neutrinocannot be observed due to its neutrality. Therefore, we would suggestSuper-Kamiokande Collaboration to re-analyze the zenith angle distribution ofthe neutrino events which occur inside the detector carefully, since L_nu andL_mu are alternative expressions of the cosine of the zenith angle for theincident neutrino and that for the emitted muon, respectively.
