Measurement of the depolarisation factor D(θ) for the reaction2H(n,n)2H at 2.45 MeV

Abstract
The angular distribution of the depolarisation factor D( theta ) has been measured for the n-2H scattering at 2.45 MeV. The incident polarised neutron beam was produced from the 12C(d,n)13N reaction at 25 degrees lab. Two sets of phase-shifts between 0 and 3.27 MeV have been determined by fitting the cross sections in the frame of effective range approximation (ERA). The experimental results are compared with these phase-shift predictions.
