Precision measurements of the electron energy distribution in nuclear beta decays KU Leuven
Although nuclear β decays have been studied for almost a century, there are still questions that can be answered through precision measurements of the energy distribution of emitted electrons. The shape of the β spectrum reflects not only the weak interaction responsible for the decay. It is also sensitive to the strong interaction which confines the decaying quark in the nucleon. The electromagnetic force also plays a role since the ejected ...
