A new anomaly observed in $^{4}$ He supports the existence of the hypothetical X17 particle

A. J. Krasznahorkay, M. Csatlós, L. Csige +7

Energy-sum and angular correlation spectra of $e^{+} e^{-}$ pairs produced in the $^{3}$ H(p, $γ$ ) $^{4}$ He nuclear reaction have been studied at $E_{p}$ =510, 610 and 900 keV proton energies…

New evidence supporting the existence of the hypothetic X17 particle

A. J. Krasznahorkay, M. Csatlos, L. Csige +8

We observed electron-positron pairs from the electro-magnetically forbidden M0 transition depopulating the 21.01 MeV 0 $^{-}$ state in $^{4}$ He. A peak was observed in their $e^{+} e^{-}$ an…
