Directional dependence of the event-by-event neutron-γ multiplicity correlations in ²⁵²Cf(sf)

RADIOACTIVITY ²⁵²Cf(SF); analyzed Eg and En data collected at the Chi-Nu array at the Los Alamos Neutron Science Center with considering the angle between the emitted particles in addition to their individual energies; deduced nγ-correlations, enhancement of γ-emission around 0.7 and 1.2 MeV, directional alignment for Eγ below 0.7 MeV, correlation between fragment excitation energies and angular momentum. Comparison with model calculations.

Structure in the event-by-event energy-dependent neutron-γ multiplicity correlations in ²⁵²Cf(sf)

RADIOACTIVITY ²⁵²Cf(SF); analyzed Eγ and E(n) data collected at the Chi-Nu array at the Los Alamos Neutron Science Center with the application of the normalized differential multiplicity covariances; deduced neutron-γ correlations, evidence for enhancements in neutron-γ correlations around Eγ=0.7 and 1.2 MeV. Comparison with model calculations. Relevance to disagreement in the literature about correlations between neutron-γ competition and fragment properties.

Event-by-event neutron-photon multiplicity correlations in ²⁵²Cf(sf)

RADIOACTIVITY ²⁵²Cf(SF); analyzed available data using unfolding techniques in comparison with predictions of model-based calculations; deduced a significant event-by-event neutron-photon emission competition following the spontaneous fission of ²⁵²Cf.
