Deuteron breakup induced by 14-MeV neutrons from inertial confinement fusion
Abstract
Measurements are reported for the angle-averaged double-differential cross section <d2σ/σ d EndΩn d End Ωn > 0∘<θ <7 .4∘ for the breakup reaction 2H(n ,2 n )1H, induced by 14-MeV neutrons generated using an inertial confinement fusion platform. A bright neutron source, created on the OMEGA Laser System [Boehly et al., Opt. Commun. 133, 495 (1997), 10.1016/S0030-4018(96)00325-2] with a luminosity of L =1024s-1 , was used to irradiate deuterated targets. The absolute yields and energy spectra from the breakup neutrons emitted in a forward-angle geometry (θ =0∘ to 7.4°) were detected with a sensitive, high-dynamic-range neutron time-of-flight spectrometer. The cross-section data, measured for neutron energy range from 0.5 to 10 MeV, is well reproduced by a theoretical calculation employing realistic nucleon-nucleon and three-nucleon forces.
