Abstract
A measurement of the energy spectrum of recoil electrons from solar neutrin o scattering in the Super-Kamiokande detector is presented. The results sho wn here were obtained from 504 days of data taken between 31 May 1996 and 2 5 March 1998. The shape of the measured spectrum is compared with the expec tation for solar B-8 neutrinos. The comparison takes into account both kine matic and detector related effects in the measurement process. The spectral shape comparison between the observation and the expectation gives a chi(2 ) Of 25.3 with 15 degrees of freedom, corresponding to a 4.6% confidence le vel.
