Study of neutron fragment angular correlations

SCINTIA, a detection array to study neutrons emitted in fission © EU, 2015

In close collaboration with several institutes from Member States (Belgium France, Germany) and Russia, scientists from the JRC-Institute for Reference Materials and Measurements (IRMM)  performed an experiment which had the aim to study neutron angular correlations in order to elucidate the neutron emission mechanisms in the fission process.

Experimental neutron angular distributions were investigated in the spontaneous fission process of 252Cf. Besides prompt neutron emission from fully accelerated fragments also so-called scission neutron emission and anisotropic emission of neutrons are nowadays included in fission models. To highlight the latter two processes a new experimental method was developed by the collaboration team.
