Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

The fire that powers the universe: Harnessing inertial fusion energy
It was a laser shot for the ages. By achieving fusion ignition on December 5, 2022, Lawrence Livermore National Laboratory proved that recreating the “fire” that fuels the sun and the stars inside a laboratory on Earth was indeed scientifically possible.

Elastic and inelastic neutron scattering cross sections of cobalt were measured from incident energies of 1.8 to 4.0 MeV including the excitation of states at 1.10 ± 0.01, 1.20 ± 0.01, 1.30 ± 0.01, 1.43 ± 0.01, 1.46 ± 0.02, 1.72 ± 0.02, 2.06 ± 0.02, 2.09 ± 0.02, 2.16 ± 0.03, 2.35 ± 0.05, and 2.50 ± 0.05 MeV. Total neutron cross sections were measured from 2.0 to 4.5 MeV. The experimental results and previously reported values are used to deduce an optical-statistical model which is descriptive of measured values to ∼20.0 MeV. The observed inelastic scattering cross sections are related to the level structure of the target isotope and are shown consistent with a nuclear structure model based upon a proton hole in the ƒ7/2 shell strongly coupled to a spherical core. A resolution to the previous ambiguities in fπ assignments is suggested. The experimental and calculational results are compared with the cross-section values given by ENDF/B-III.
