摘要：

We make a global vacuum neutrino oscillation analysis of solar neutrino data, including the seasonal and energy dependence of the recent Super-Kamiokande 708-day results. The best fit parameters for v(e), oscillations to an active neutrino are delta m(2) = 4.42 X 10(-10) eV(2), sin(2)2 theta = 0.93. The allowed mixing angle region is consistent with bi-maximal mixing of three neutrinos. Oscillations to a sterile neutrino are disfavored. Allowing an enhanced hep neutrino flux does not significantly alter the oscillation parameters. (C) 1999 Elsevier Science B.V. All rights reserved.
