Investigation of the antineutrino angular distribution in experiments on the β decay of polarized neutrons

Internal and external optical bremsstrahlung accompanying the β decay of polarized nuclei were investigated. The features of angular distribution of light photons were analyzed taking into account multiple electron scattering. Monte-Carlo simulation was used to study the fate of β electrons and to calculate the intensity and angular distribution of the optical photons. It is shown that in pure water, the contribution of secondary electrons in the production of photons reaches 30–40%. We suggest using the angular distribution of optical photons to study the polarization states of β isotopes imbedded in transparent media.

Decay Asymmetry

We obtain three independent values of the effective vector coupling constant [Formula: see text] for nuclear β-decay by using various pieces of experimental data (the neutron life-time and the β-decay asymmetry of polarized neutrons, data on the decays of kaons and hyperons, and the ft values of superallowed β+ decays). For superallowed decays we discuss various analyzes of the data. The reliability and consistency of the values of [Formula: see text] obtained in the different ways is assessed.
