Breaking ground on a new approach to construction
The drive to Kairos Power’s reactor demonstration site in Oak Ridge, Tenn., is not only scenic—it’s historic. Nearly 85 years ago, roughly 30,000 construction workers transformed orchards and farmland into a key Manhattan Project site. Depending on your route, you may pass by one of the three gatehouses that were once military checkpoints controlling access to Atomic Energy Commission production facilities.

Double-differential cross-section formulations are presented of a light composite particle projectile considering pickup-type reactions with one and two particles above the Fermi sea by using energy-averaged and energy-angle correlated kernels, respectively. The calculated results of cross sections, spectra, and double-differential cross sections indicate that generally the contributions of the pickup-type reactions with two particles above the Fermi sea are ∼15 to 25% when the incident energies are <50 MeV and become dominant when the incident energies are >50 MeV in some region of the outgoing energies and angles, whereas the forward tendency of the calculated angular distributions by the pickup configuration with two particles above the Fermi sea is weaker than that by the pickup configuration with one particle above the Fermi sea. The energy-angle correlation must be considered for the reactions of the outgoing composite particle with a higher incident energy.
