摘要：

Data on internal pair conversion in some high energy magnetic nuclear transitions exhibit an excess in e(+)e(-) pairs around 9 MeV/c(2) invariant mass. While the deviations individually may be circumstantial, in combination they appear to point to a common anomaly, which can be explained to the emission of a short-lived isoscalar pseudoscalar neutral boson.
