Confirmation of the existence of the X17 particle
In a 2016 paper, an anomaly in the internal pair creation on the $M1$ transition depopulating the 18.15 MeV isoscalar 1$^+$ state on $^8$Be was observed. This could be explained by the creation and subsequent decay of a new boson, with mass $m_Xc^2$ = 16.70 MeV. Further experiments of the same trans...
