Cross section for the reaction
and fundamental characteristics of the weak interaction
Mikaelyan L. A., Skorokhvatov M. D. , Etenko A. V.
A "worldwide average" value has been found for the cross section for inverse β decay for reactor antineutrinos: σ6*1* = 6.32 X 10~43 cmVfission (235U) ± 3.3% The axial constant has also been found: gv/ = (1.78 Χ 1G~49 ± 2,6%) erg · cm3. This value agrees with the value found for the constant gnA from neutron decay: gJ/gA = 100 ± 2.8%. The polarization of the neutrinos, hv = 1,00 ± 4.7%, agrees with the absence of right-hand currents.
