Calculated spectra of antineutrinos from the fission products of /sup 235/U, /sup 238/U, and /sup 239/Pu, and antineutrino-induced reactions
The theoretical spectra of antineutrinos from the beta decays of the products of fissioning /sup 235/U, /sup 238/U, and /sup 239/Pu were recalculated using recent compilations of the level structure, beta branching ratios, and fission yields. In addition, a very recent semiempirical mass formula, particularly designed to achieve local accuracy on the (N,Z) plane, was used to calculate the beta Q values of isotopes of unknown decay schemes. Recent decay systematics, far from the beta stability line, have encouraged us to assume that most of the levels of the isotopes of a given Z, differing by ..delta..N=2, are very similar in order and in energy. The beta spectrum from equilibrium, thermal fission products of /sup 235/U was calculated and compared with existing experimental data. Theoretical predictions are presented for the inverse beta decay of the proton, the neutral current disintegration of the deuteron, and the excitation of /sup 7/Li by antineutrinos. Existing data from the elastic scattering of electrons by antineutrinos are reanalyzed with the present antineutrino spectra. The result is that these data agree with the predictions of the Weinberg-Salam model with (0.24
