Abstract
The total energy of the alpha particles, which resulted from the decay of 8B, was measured. A beam of 8B ions was implanted near the midplane of a planar Si detector. This eliminated α-particle energy loss in insensitive regions and allowed the sum energy of the two α particles to be observed with a single detector. The measurement of the 8B β-delayed α apectrum provided direct determination of the 8B neutrino spectrum.
