Interaction of 24.0- and 27.2-MeV neutrons with deuterons

The angular distributions of 24.0- and 27.2-MeV neutrons scattered elastically by deuterons through angles between 90 and 166 ° (c.m.) were measured. Proton-emission energy spectra were studied at 11 and 22 ° (lab) and angular distributions were measured between 11 and 46° (lab). The spectra and angular distributions were normalized to the n-p differential cross section at 158° (c.m.). The minimum cross sections of neutrons elastically scattered by deuterons were found to be less than the minimum cross sections of elastically scattered protons.[NUCLEAR REACTIONS ²H(n,d), (n,p), E=24.0, 27.2 MeV; measured $\sigma \left({\theta }_n\right)$, ${\theta }_n=90-{166}^{\circ }$ (c.m.), $\Delta {\theta }_n=5.6-{10.0}^{\circ }$; measured $\sigma \left({\Theta }_p\right)$, ${\Theta }_p=11-{45}^{\circ }$ (lab), $E_p\ge 10$ MeV, $\Delta {\Theta }_p=5-6^{\circ }$ (lab); measured $\sigma (E_p,\Theta )$, $\Theta =11,{22}^{\circ }$ (lab), $E_p\ge 10$ MeV, $\Delta \Theta =5^{\circ }$.
