The Angular Distribution ofLi6(n, α)H3for Neutrons of 200, 270, 400, and 600 kev

Abstract

The angular distribution of ${\mathrm{Li}}^6(n, \alpha ){\mathrm{H}}^3$ has been measured for neutron energies of 200, 270, 400, and 600 kev by determining the distribution of triton tracks from this reaction in Ilford $C2\mathrm{}$ plates loaded with enriched ${\mathrm{Li}}^6$. The results fit a series of the type $A+B{cos\phi }_0+C{{cos}^2\phi }_0$, where ${\phi }_0$ is the neutron-triton angle in the center-of-mass system. This indicates that the $s$ and $p$ components of the incident neutron wave predominate in the interaction.
