Recently, we observed anomalous internal pair creation for the M1 transition depopulating the 18.15 MeV isoscalar 1+<\/sup>\u00a0state in\u00a08<\/sup>Be. We observed a significant (\u03c3<\/i>\u00a0= 7.37) peak-like deviation from the predicted angular correlation of the e+<\/sup>\u00a0e pairs at\u00a0\u03b8<\/i>\u00a0= 140\u00b0. To the best of our knowledge no nuclear physics related description of such deviation can be made. However, the deviation can be described by assuming the creation and subsequent decay of a boson with mass of \u224817 MeV. In order to clarify the interpretation, we re-investigated the\u00a08<\/sup>Be anomaly with an improved, and independent setup. We have confirmed the signal of the assumed X(17) particle and constrained its mass (m<\/i>0<\/sub>c<\/i>2<\/sup>\u00a0= 17.01(16) MeV) and branching ratio compared to the \u03b3-decay (B<\/i>x<\/i><\/sub>\u00a0= 6(1)\u00a0\u00d7<\/b>\u00a010\u22126<\/sup>).<\/p>\n<\/div>\n
