Cross-section Measurements of $^{11}$B($n$, $n' \gamma$)

ORAL

Abstract

Excitation of high-energy states in $^{11}$B via inelastic neutron scattering is important to nuclear reaction studies. Measurements of the above reaction were conducted at LANL at the LANSCE facility. A 4.5~$mm$ thick target of $^{11}$B was bombarded with a continuum energy-spectrum of neutrons produced from a spallation source at the LANSCE facility at LANL. High-energy gamma-rays were measured using HPGe detectors in the GEANIE array. The neutron energies were determined by the time-of-flight technique. We will present and discuss results for the cross-section measurements of $^{11}$B($n$, $n' \gamma$). We will compare and contrast the results with previous measurements.

*Work performed under the auspices of the US DOE by University of California, LLNL under contract W-7405-Eng-48 and LANL under contract W-7405-ENG-36, and benefited from the use of the LANSCE accelerator supported under contract W-7405-ENG-36
