Angular Correlations Between Fragment Spin and Prompt Neutron Evaporation in Spontaneous Fission of $^{252}$Cf: CORA-Demon Experiment
International audience A novel method to search for the anisotropic emission of prompt neutrons in the center-of-mass system of fission fragments is presented. The anisotropy is conjectured to be due to the large spins of fission fragments are known to carry. Triple neutron- neutron-fragment correla...
