TLDR
In this article, the spin dependence in the scattering of 14 MeV electrons from Pb as a function of scattering angle and foil thickness was investigated and extrapolated to infinitely thin targets were in excellent agreement with theory if the finite nuclear size is taken into account.Abstract:
To aid fundamental studies on the polarization of electrons in beta decay, measurements were made of the spin dependence in the scattering of 14 MeV electrons from Pb as a function of scattering angle and foil thickness. The experiment made use of a beam of polarized electrons from a strained GaAsP cathode. A simple theoretical model based on plural scattering explains the observed dependence of the analyzing power on foil thickness. The results extrapolated to infinitely thin targets are in excellent agreement with theory if the finite nuclear size is taken into account.read more

New physics searches in nuclear and neutron $\beta$ decay
TL;DR: In this paper, a new global fit of available β-decay data is performed incorporating, for the first time in a consistent way, superallowed $0+to 0+$ transitions, neutron decay and nuclear decays.

The Sherman function in highly relativistic elastic electron–atom scattering
TL;DR: In this paper, the Sherman function is calculated within the relativistic partial wave representation for a target with a beam energy near 80 MeV, and the experimental results show that it is a measure of spin asymmetry in the elastic scattering of transversely polarized electrons from heavy targets.
