Forward-angle neutron-proton scattering at 96 MeV

Abstract

The differential np scattering cross section has been measured at 96 MeV in the angular range θ c.m. = 20 • -76 • . Together with an earlier data set at the same energy, covering the angles θ c.m. = 74 • -180 • , a new data set has been formed in the angular range θ c.m. = 20 • -180 • . This extended data set has been normalized to the experimental total np cross section, resulting in a renormalization of the earlier data of 0.7%, which is well within the reported normalization uncertainty for that experiment. A novel normalization technique has been investigated. The results on forward np scattering are in reasonable agreement with theory models and partial wave analyses and have been compared with data from the literature.

Experiments and Theoretical Data for Studying the Impact of Fission Yield Uncertainties on the Nuclear Fuel Cycle with TALYS/GEF and the Total Monte Carlo Method

“…[13]). The use of either the same or different standard cross sections for normalization of differential experimental data leads to correlations between data sets on the one hand and systematic discrepancies between data sets on the other hand.…”

C/O Kerma coefficient ratio for 96 MeV neutrons deduced from microscopic measurements

“…The experimental cross section data have all been obtained at TSL and are mainly from the Medley (Tippawan et al, 2006(Tippawan et al, , 2009a(Tippawan et al, , 2009bBevilacqua et al, 2009) and SCANDAL (Klug et al, 2003;Johansson et al, 2005;Andersson et al, 2009) setups. These data are completed with results from model calculations to allow calculation of total Kerma coefficients.…”

“…Partial Kerma coefficients for proton, deuteron, triton, 3 He and a particle production were deduced for hydrogen, carbon and oxygen from microscopic double differential cross-section data (Rahm et al, 2001;Klug et al, 2003;Johansson et al, 2005;Tippawan et al, 2006Tippawan et al, , 2009a. Calculations were also performed for various elements and tissue compositions.…”

Neutrons for Science and Industry — Uppsala Neutron Beam Activities

“…Previously, a series of backward-angle np scattering experiments have been undertaken [6,7,8,9]. Recently, these measurements have been complemented by a measurement at forward angles at 96 MeV [10,11]. In addition, a novel method to study backward-angle np scattering by tagging techniques has recently been developed at IUCF, and it is described in another contribution to this conference [12].…”
