Abstract A measurement of the electron spectrum from the thermal neutron fission of U/sup 235/ is described. From this spectrum the antineutrino spectrum is calculated, and on the basis of the two-component theory of the antineutrino a predicted average cross section for the absorption of antineutrinos by protons is (6.1 the J-57 engin 1) x 10/sup -43/ cm/sup 2/fission. This agrees with the measured cross section of (8.7 the J-57 engin 1.5) x 10/sup -43/ cm/sup 2/ fission. The four-component theory of the antineutrino would have predicted (5.05 the J-57 engin 0.5) x 10/sup -43/ cm/sup 2/fission. (auth)
