Precision Measurement of the Neutron Beta-Decay Asymmetry

M. P. Mendenhall, R. W. Pattie, Y. Bagdasarova +38

A new measurement of the neutron -decay asymmetry has been carried out by the UCNA collaboration using polarized ultracold neutrons (UCN) from the solid deuterium UCN sour…

Neutron Beta Decay Studies with Nab

S. Baeßler, R. Alarcon, L. P. Alonzi +31

Precision measurements in neutron beta decay serve to determine the coupling constants of beta decay and allow for several stringent tests of the standard model. This paper discuss…

Lutetium thermometry for Oklo natural reactors: a new look at old data

C. R. Gould, E. I. Sharapov

Lutetium thermometry has been used to analyze Oklo natural nuclear reactor zones but leads to widely varying and puzzling predictions for the temperatures which in turn impac…
