Angular distributions and yield of the 13C(d,p)14C reaction

Abstract

Angular distributions have been measured of long-range protons from the 13C(d,p)14C reaction at six deuteron energies between 0.30 MeV and 0.65 MeV. Protons were detected using nuclear emulsions. The target consisted of a thin layer of almost pure 13C on a thin aluminium backing. The experimental angular distributions agree surprisingly well with Butler's theory (for linn = 1), which seems to indicate that even at these low deuteron energies the 13C(d,p)14C reaction proceeds predominantly by stripping.

The yield in the forward direction (θ = 0°) also was measured for deuteron energies between 0.25 MeV and 0.675 MeV at 25 keV intervals and for θ = 120° between 0.50 MeV and 0.70 MeV at 10 keV intervals. Use was made of a thin crystal (NaI) scintillation spectrometer. Indications were found of a resonance at about 0.63 MeV.
