Heisenberg's uncertainty principle in the PTOLEMY project: a theory update

PTOLEMY Collaboration, A. Apponi, M. G. Betti +58

We discuss the consequences of the quantum uncertainty on the spectrum of the electron emitted by the -processes of a tritium atom bound to a graphene sheet. We analyze quantita…

Implementation and Optimization of the PTOLEMY Transverse Drift Electromagnetic Filter

A. Apponi, M. G. Betti, M. Borghesi +53

The PTOLEMY transverse drift filter is a new concept to enable precision analysis of the energy spectrum of electrons near the tritium beta-decay endpoint. This paper details the i…

Response of Windowless Silicon Avalanche Photo-Diodes to Electrons in the 90-900 eV Range

Alice Apponi, Gianluca Cavoto, Marco Iannone +5

We report on the characterization of the response of windowless silicon avalanche photo-diodes to electrons in the 90-900 eV energy range. The electrons were provided by a monoener…

Electron correlation effects in the exchange coupling at the Fe/CoO/Ag(001) ferro-/antiferro-magnetic interface

Marco Sbroscia, Adriano Verna, Giovanni Stefani +8

Angle resolved-Auger-photoelectron coincidence spectroscopy (AR-APECS) has been exploited to investigate the role that electron correlation plays in the exchange-coupling at the fe…

Unexpectedly large electron correlation measured in Auger spectra of ferromagnetic iron thin films: orbital-selected Coulomb and exchange contributions

R. Gotter, A. Verna, M. Sbroscia +7

A set of electron-correlation energies as large as 10 eV have been measured for a magnetic 2ML Fefilm deposited on Ag(001). By exploiting the spin selectivity in angle-resolved Aug…
