Extreme back anglenH2elastic scattering at 794 MeV

Abstract

The cross section for elastic scattering of 794-MeV neutrons by deuterium has been measured for neutron center of mass angles from 139' to 179'. The angular distribution is fitted very well both by an empirical function ae"'" "i«' and by a calculation that uses the one parameter Craigie

“…Very close to scattering angles θ p = 180 • experimental data are absent. The only comparable measurement in the angular range up to about 179 • was carried out at 0.794 GeV in nd → dn scattering [49]. The observed angular dependence in the range 171.8 • -178.57 • is flat, quite similar to our measurement at 0.8 GeV (see Fig.…”

“…with a smooth energy dependence of the coefficients A(T p ) and B(T p ) in the range T p = 0.4-1.0 GeV. The luminosities obtained this way and from the method described in the previous paragraph were compared at 0.8 GeV and were found to be consistent within 20%, which is quite reasonable since the available data at 0.8 GeV [46,49,50] agree only within 15%.…”

“…As shown in Fig. 3, the selected deuterons produce a clean peak in the momentum distributions, and the data were normalized to the available experimental data [38,[44][45][46][47][48][49] obtained under similar kinematical conditions. Based on the available data, an interpolation was carried out, using an empirical expression…”
