“…The Q-value for this reaction is 15 MeV, however there is a high probability to excite residual levels in the resultant 8 Be nucleus, which will result in lower energy neutrons as compared to elastic reactions. 16 To determine the neutron energy spectrum, neutron time-of-flight spectrometers (nTOF) were placed 4.54 m and 4.69 m away from the target at 17.5 and 157.5 from target normal, respectively. The nTOFs measure the travel time of neutrons from source to detector to deduce their kinetic energy.…”

“…Additionally, the probability of an inelastic interaction is much greater than the probability of an elastic interaction for deuterons in Li. 16 Also, the deuteron spectrum is exponential so the majority of ions reside at lower energies. None of these effects prevent 8 MeV deuterons from generating neutrons from elastic interactions, but the number of neutrons may be decreased to a level that was below the nTOF detection limit.…”

The generation of high-energy neutrons using laser-accelerated ions is demonstrated experimentally using the Titan laser with 360 J of laser energy in a 9 ps pulse. In this technique, a short-pulse, high-energy laser accelerates deuterons from a CD 2 foil. These are incident on a LiF foil and subsequently create high energy neutrons through the 7 Li(d,xn) nuclear reaction (Q ¼ 15 MeV). Radiochromic film and a Thomson parabola ion-spectrometer were used to diagnose the laser accelerated deuterons and protons. Conversion efficiency into protons was 0.5%, an order of magnitude greater than into deuterons. Maximum neutron energy was shown to be angularly dependent with up to 18 MeV neutrons observed in the forward direction using neutron time-of-flight spectrometry. Absolutely calibrated CR-39 detected spectrally integrated neutron fluence of up to 8 Â 10 8 n sr À1 in the forward direction.

“…This code is an extension to MCNP-4C with the capability of simulating the generation of neutrons, c-rays and other d-Li reaction products on the basis of evaluated Li(d,xn) data [4]. Neutron cross sections from general purpose high energy libraries [5,6] were used for the transport and nuclear response calculations.…”

“…By applying a new methodology including compound nucleus, pre-equilibrium, stripping and direct interactions, the d + 6,7 Li cross-section data evaluations were recently updated to 50 MeV [12,13]. Experimental thick target neutron yield data can be reproduced with significant better accuracy than with previous d-Li data and other methodological approaches.…”
