An analysis of the Mikheyev-Smirnov-Wolfenstein effect using 1040 days of Kamiokande-II data is reported, which provides constraints on neutrino-oscillation parameters. The measured recoil-electron energy spectrum alone leads to the conclusion that the adiabatic region, 7.2×10-4<sin22 <6.3×10-3, 1.3×10-4 (eV)2, is disfavored at the 90% confidence level.
