Correlated Neutron Emissions from ²⁵²Cf

This paper presents new experimental results of correlated, prompt neutron emission from the spontaneous fission of ²⁵²Cf. Specifically, we present correlated-neutron emission probabilities and average energies for two detected neutrons as a function of the angle between the two neutrons. Experimental results are compared to several Monte Carlo models that include the number, energy, and angular distributions of prompt neutrons from fission.
