Title: MSW effects in vacuum oscillations

Abstract

We point out that for solar neutrino oscillations with the mass-squared difference of {Delta}m{sup 2} {approx} 10{sup -10} - 10{sup -9} eV{sup 2}, traditionally known as ''vacuum oscillation'' range, the solar matter effects are non-negligible, particularly for the low energy pp neutrinos. One consequence of this is that the values of the mixing angle {theta} and {pi}/2 - {theta} are not equivalent, leading to the need to consider the entire physical range of the mixing angle 0 {le} {theta} {le} {pi}/2 when determining the allowed values of the neutrino oscillation parameters.
