ABSTRACT
The search for solar neutrinos illustrates not only the use of the neutrino as a tool but also the fruitful interaction of theory and experiment. One could argue that there was no serious discrepancy between experiment and theory because the experiment had set only an upper limit for solar neutrinos and because both the experimental result and the theoretical prediction had significant uncertainties. There was also the possibility that the apparatus could not detect solar neutrinos. The energy calibration, the angular resolution and reconstruction, and the interaction position were of crucial importance in the experiment: To observe solar neutrinos in a detector such as Kamiokonde II, it is important to calculate accurately the true energy, interaction position, and direction of an event. The latest results from Super Kamiokonde, a much larger version of Kamiokonde, has confirmed the solar neutrino problem.
