| Popis: |
Electron-positron angular correlations were remeasured for the 17.6 MeV ( J π = 1 + → 0 + ) ground state transition in 8 Be using an improved setup compared to the one we used previously. Significant deviations from the internal pair creation was observed at large angles in the angular correlations, which supports that, in an intermediate step, a neutral isoscalar particle with a mass of 17.0 ±0.2(stat) ±0.5(sys) MeV/ c 2 and J π = 1 + was created. |
