Range Distribution of the Charged Particles from the D-D Reactions for 10-Mev Deuterons: Differential Elastic Scattering Cross Section at 40 Degrees, 60 Degrees, and 80 Degrees in the Center-of-Mass System

Microphotographic techniques have been used to obtain the range distribution of the charged particles resulting from the D - D reactions at center of mass angles of 40 degrees, 60 degrees, and 80 degrees for 10-Mev deuterons. At 80 degrees all of the groups of charged particles from the above reactions are clearly resolved. The differential D - D elastic scattering cross sections have been obtained for the same angles and for these angles the cross sections per unit solid angle in the center-of-mass system are in the ratios of 1.00:0.51:0.42, respectively. Only one group of protons is observed from the D(d,H)H³ reaction, thus indicating that the H³ nucleus is not formed in an excited state for the energy region investigated when He⁴ is the compound nucleus.
