On the Bombardment ofLi2O and C by Alpha-Particles and Deuterons

Abstract

Photographic nuclear emulsions were used to record the scattered and recoiling particles when ${\mathrm{Li}}_2$O and C targets were each independently bombarded by 10-Mev deuterons and 20-Mev alpha-particles. The 1.0-Mev level in ${\mathrm{C}}^{13}$ has been confirmed and a new level at 6.8 Mev in ${\mathrm{C}}^{13}$ has been determined. The relative scattering of deuterons and alpha-particles from nuclei in the ground state and in their various nuclear energy levels are illustrated. Finally the alpha-particle range-energy curve, as applied to Ilford E-1 nuclear emulsions, has been modified at higher energies.
