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

NUCLEAR REACTIONS ²H(n, 2n)¹H, E=14 MeV, [neutron beam from inertial confinement fusion platform using the OMEGA Laser System at the University of Rochester]; measured E_n, I_n emitted by deuteron breakup using a TOF spectrometer with liquid scintillators; deduced angle-averaged double differential σ (E_n=0.5 to 10 MeV), contributions from the neutron-induced deuteron breakup from the difference in spectra obtained from a deuterated and the corresponding nondeuterated reaction vessel. Neutrons generated in the deuteron breakup reaction modeled using the neutron transport code MCNP. Experimental results compared to model calculations employing realistic nucleon-nucleon (NN) and 3N forces.
