Gamma Rays from the Deuteron Bombardment of Be9, B10, N14, and F19

Abstract

A magnetic lens pair spectrometer has been used to study the radiations produced by the bombardment of certain light nuclei with deuterons from a Van de Graaff accelerator. Gamma rays from the bombardment of ${\mathrm{Be}}^9$ with 2.5-Mev deuterons were observed at 6.00±0.06, 5.10±0.1, and 4.52±0.1 Mev. At 3.85-Mev bombarding energy no lines were observed between 6.5 and 8.0 Mev with an intensity as great as 5 percent of that of the 6.0-Mev line. Gamma rays from the bombardment of ${\mathrm{B}}^{10}$ with 2.0-Mev deuterons were observed at 8.93±0.04, 8.57±0.04, 7.30±0.03, 6.75±0.03, 6.50±0.03, 5.03±0.03, 4.73±0.03, and 4.49±0.05 Mev. Gamma rays from the bombardment of ${\mathrm{N}}^{14}$ with 4.0-Mev deuterons were observed at 10.73±0.08, 10.04±0.04, 9.13±0.06, 8.33±0.04, 7.31±0.04, 6.81±0.04, 6.33±0.05, 6.12±0.06, and 5.26±0.04 Mev. Gamma rays from the bombardment of ${\mathrm{F}}^{19}$ with 3.6-Mev deuterons were observed at 11.51±0.2, 10.61±0.1, 9.97±0.1, and 9.34±0.1 Mev. All the energies of gamma rays given above are corrected for Doppler shifts.
