Correlations between energy and γ-ray emission in ²³⁹Pu(n, f)

NUCLEAR REACTIONS ²³⁹Pu(n, f), E=2-40 MeV; measured fragments, En, In, Eγ, Iγ, (fragments)γ-coin, (fragment)n-coin, nγ-coin; deduced γ spectrum, γ multiplicity, linear relation between incident neutron energy and γ multiplicity. Comparison to fission model calculations done with CGMF, FIFRELIN and FREYA codes. Multiplicity results are compared to ENDF/B-VIII.0 data and to experimental data on ²³⁸U(n, F), ²³⁹Pu(d, F), ²³³Pu(d, F), ²⁴⁰Pu(d, F) reactions. Broad-spectrum neutron beam produced via spallation reaction of an 800 MeV proton beam on W target (Los Alamos Neutron Science Center). Chi-Nu liquid scintillator array, a hemispherical array of 54 EJ-309 (n- and γ- measurement) surrounding multifoil parallel-plate avalanche counter (PPAC) serving as target and contain ing ²³⁹Pu (fragment measurement).

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.
