Low-energy Cross Section of the D-D Reaction and Angular Distribution of the Protons Emitted
U.S. Atomic Energy Commission, Technical Information Division, 1950 - Cross sections (Nuclear physics). - 38 pages
The thick target yield of the reaction D + D yields T + p + 3.98 Mev has been measured, using a heavy ice target, and observations have been made on the angular distribution of the protons. Experiments have been carried out in the region 15 Kev to 105 Kev incident deuteron energy. Evidence has been obtained that, even for very small bombarding energies, the angular distribution of protons in the center-of-gravity (c.g.) system does not become Isotropic. The variation of the cross section with energy can only approximately be represented by a Gamow function.
