The Solar Neutrino Problem

A few years ago Fowler (1972) published a paper in which he proposed two ‘desperate explanations’ for the solar neutrino problem. Desperation continues to be characteristic of the subject, for, in spite of many investigations over recent years, there is still no unambiguously successful model satisfying all the observational features of the Sun and giving a predicted neutrino count rate below the Davis (1972) experimental limit.
