Deuteron breakup induced by 14-MeV neutrons from inertial confinement fusion

Measurements are reported for the angle-averaged double-differential cross section < d(2)sigma/dE(n)d Omega(n)>(0)degrees( <) (theta < 7.4)degrees for the breakup reaction H-2(n, 2n)H-1, 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)] with a luminosity of L = 10(24)s(-1), was used to irradiate deuterated targets. The absolute yields and energy spectra from the breakup neutrons emitted in a forward-angle geometry (theta = 0 degrees to 7.4 degrees) 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.
