In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

Total neutron cross sections of bismuth were measured with resolutions of < 3 keV over the energy range 0.2 to 1.4 MeV. Differential elastic-scattering cross sections were determined at intervals < 50 keV from 0.3 to 1.5 MeV with resolutions of ∼20 keV. The inelastic-neutron excitation of a state at 896 ± 1 keV was observed and the respective differential excitation cross sections determined with incident resolutions of ≥12 keV. Partially resolved resonance structure was evident in all the measured values. The experimental results were assayed for possible intermediate structure and were compared with the results of optical model and statistical calculations. The model calculations were inclusive of contributions due to the fluctuation and correlation of compound-nucleus resonance widths and of the shell closure at N = 126.
