Backscattering Study of Electrons from 0.1 to 3.4 MeV Open
Benchmarking simulation codes for electron transport and scattering in matter is a crucial step for estimating uncertainties in many applications. However, experimental data for electron energies of a few MeV is scarce to make such compari…

Influence of the recoil-order and radiative correction on the decay correlation coefficients in mirror decays Open
Measurements of the beta decay correlation coefficients in nuclear decay aim\nfor a precision below $1\\%$ and theoretical predictions should follow this\ntrend. In this work, the influence of the two dominant Standard Model\ncorrection te…

Scalar current limit from the beta-neutrino correlation: the WISArD experiment Open
Beta - neutrino correlation measurements are key in the research of physics beyond the Standard Model. In pure Fermi beta transitions, the beta-neutrino correlation coefficient, a βν , is sensitive to the presence of scalar currents. The p…
