The D (p,[gamma])He³ reaction at low energies

University of British Columbia

A detailed study has been made of the D(p ,γ)He³ reaction at proton energies of 300 kev, 600 kev, and 1.0 Mev. In order to measure the absolute cross section for this reaction the efficiency of a 2.5 inch by 3.5 inch sodium iodide crystal scintillation counter was measured by simultaneous alpha particle and gamma ray measurements on the 340 kev resonance of F¹⁹ (p,α,γ)O¹⁶. The efficiency of the counter for the 6.14 Mev gamma radiation from this resonance has a measured value of 0.612 ± 0.009. The angular distribution of the gamma radiation from the D(p,γ)He³ reaction has been found to have the form A(sin²θ + b) where b equals 0.0795 ± 0.010, 0.032 ± 0.004 and 0.024 ± 0.003 at proton energies of 300 kev, 600 kev and 1.0 Mev respectively. The absolute cross section of this reaction has been measured at proton energies of 300 kev and 1.0 Mev using the above calibrated scintillation counter. The cross section has been found to be (0.898 ± 0.097) X 10⁻³º square centimeters at a proton energy of 300 kev and (3.24 ± 0.35)X 10⁻³º square centimeters at a proton energy of 1.0 Mev.
