Results of solar neutrino observations by the Kamiokande (ν_ee→ν_ee Experiment), Chlorine and Gallium Experiments are in apparent disagreement among them. However, it is necessary to consider possible errors before making such a judgement. We have comments on the Kamiokande II results to point out as followings; (1) in the Kamiokande II paper there seems a serious disconsistency in the expected event rate of the Standard Solar Model(SSM) calculation between their used value in derivations of the data/SSM and their calculated value due to the Bahcall and Ulrich theory. Using the correct expected value for the SSM, we obtain a value of 0.35 for the data/the SSM in a place of 0.46. (2) The Kamiokande group has concluded that the observed cos 0 distribution of collimated 7 rays with the Ni(n,7)Ni^* source endorses the proper procedure of Monte Carlo simulations using the EGS4 code for angular distributions in the reaction of ν_ee→ν_ee. However, Smirnov-Cramer-Von Mieses test for the goodness-of-fit gives a poor significance probability of less than 0.001. (3) Using more adequate scattering formulae instead of EGS4 code which is used in the Kamiokande analysis, we can show 0.31 ± 0.14 for the data/the SSM with Mott formula and 0.33 ± 0.14 for Williams formula to the Kamiokande II data.
