Inverse Beta Decay and the Two-Component Neutrino

Abstract

Several procedures for calculating the average cross section per antineutrino from ${\mathrm{U}}^{235}$ fission are given to test the predictions of the two-component neutrino theory. A firm lower limit of ${\overline{\sigma }}_p>7\mathrm{}\times {10}^{-44\mathrm{}}$ ${\mathrm{cm}}^2$ is deduced from the known decays of the fission products. Three different procedures, if weighted equally, give a "best value" of ${\overline{\sigma }}_p=14\mathrm{}\times {10}^{-44\mathrm{}}$ ${\mathrm{cm}}^2$ to be compared with the recently increased experimental value ${\overline{\sigma }}_p=11\mathrm{}\pm 4\times {10}^{-44\mathrm{}}$ ${\mathrm{cm}}^2$. It is concluded that predictions of the two-component neutrino theory are in accord with the experimental results on inverse beta decay.
