Abstract
Solar neutrinos from B-8 decay have been detected at the Sudbury Neutrino O bservatory via the charged current (CC) reaction on deuterium and the elast ic scattering (ES) of electrons. The flux of nu (e)'s is measured by the CC reaction rate to be phi (CC)(nu (e)) = 1.75 +/-0.07(stat)(-0.11)(+0.12)(sy st) +/-0.05(theor) x 10(6) cm(-2) s(-1). Comparison of phi (CC)(nu (e)) to the Super-Kamiokande Collaboration's precision value of the flux inferred f rom the ES reaction yields a 3.3o sigma difference, assuming the systematic uncertainties are normally distributed, providing evidence of an active no n=nu (e) component in the solar flux. The total flux of active B-8 neutrino s is determined to be 5.44 +/-0.99 x 10(6) cm(-2) s(-1).
