Abstract

A new nuclear reaction channel on 197Au with the neutron as a projectile and a bound dineutron (2n) as an ejectile 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 the 196Au nucleus. The dineutron was identified by statistically significant radioactivity detection due to decay of Au nuclei. Cross-sections for the 197Au Au reaction are determined as and 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.
