Query: Statistically significant observation of and cross sections for a new
  nuclear reaction channel on 197Au with bound dineutron escape   A new nuclear reaction channel on 197Au with the neutron as a projectile and
a bound dineutron (^2n) in the output channel is considered based on available
experimental observations. The dineutron is assumed to be formed as a
particle-satellite, separated from the volume but not from the potential well
of 196Au nucleus. The dineutron was identified by statistically significant
radioactivity detection due to decay of 196gAu nuclei. Cross sections for the
197Au (n,^2n) 196gAu reaction are determined as 180 +/- 60 microbarns and 37
+/- 8 microbarns for [6.09-6.39] and [6.175-6.455] MeV energy ranges,
correspondingly. Possible outcomes of dineutron detection near the surface of
deformed nuclei are also raised and discussed.
