Differential cross sections for the elastic scattering of various hydrogen and helium isotopes have been measured using accelerated particles from the Los Alamos 42-inch cyclotron. The scattering of protons and deuterons from deuterons, tritons, and helium-three particles has been studied over an energy range of 5 to 14 Mev. The elastic scattering of \ensuremath{\sim}10-Mev polarized protons has also been studied. In all cases nuclear emulsions were used as detectors.Proton-deuteron elastic scattering has been measured at 5.6 and 7.85 Mev. A comparison is made to results at nearby energies of both $p\ensuremath{-}D$ and $n\ensuremath{-}D$ scattering and to theoretical predictions. The scattering of 10-Mev polarized protons from deuterons has been measured and provides support for calculations using central force approximations.Measurements of $p\ensuremath{-}T$ and $p$-${\mathrm{He}}^{3}$ elastic scattering at 6.5 and 8.34 Mev give angular distributions which are quite similar to those for $p\ensuremath{-}D$ and $p$-${\mathrm{He}}^{4}$. An encouraging agreement is found with resonating-group calculations with central-force approximations of the Serber type.Deuteron-deuteron scattering has been measured at 6.0, 8.2, 12.1, and 13.8 Mev. A preliminary theoretical treatment indicates that the process is predominantly hard-sphere scattering with no strong level splitting.Deuteron-triton and deuteron-helium three scattering has been measured over the energy range of 5 to 14 Mev. The results for the two processes are almost indistinguishable at the present level of accuracy. |
