Deuteron breakup induced by 14-MeV neutrons from inertial confinement fusion
© 2019 American Physical Society. Measurements are reported for the angle-averaged double-differential cross section (d2σ/σdEndωndEndωn)0<θ<7.4 for the breakup reaction H2(n,2n)H1, 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.
