Shake-up and shake-off spectra in the electron capture decay of atomic Be

Mauro Guerra, Inwook Kim, Stephan Friedrich +33

The most stringent laboratory-based experimental limits on the existence of sub-MeV sterile neutrinos are currently set by decay spectroscopy of radioactive Be embedded into su…

Comparison of an OGS/Polystyrene scintillator (BSO-406) with pure OGS (BSO-100), EJ-276, EJ-309, and M600 scintillators

M. Grodzicka-Kobylka, T. Szczesniak, L. Adamowski +6

In this paper, we present an investigation into the scintillation properties and pulse shape discrimination (PSD) performance of the new BSO-406, which is a blend of 40% organic gl…

Direct Experimental Constraints on the Spatial Extent of a Neutrino Wavepacket

Joseph Smolsky, Kyle G Leach, Ryan Abells +35

Despite their high relative abundance in our Universe, neutrinos are the least understood fundamental particles of nature. They also provide a unique system to study quantum cohere…
