Angular distributions of protons from the c13(d, p)c14 and c12(d, p)c13 reactions

Abstract

Angular distributions have been measured of protons from the groundstate transitions of the reactions C13(d, p)C14 and C12(d, p)C13 at a deuteron bombarding energy of 470 keV. The target consisted of barium carbonate enriched to 56% in C13 content.

The angular distribution of C13(d, p)C14 protons shows a pronounced maximum in forward direction and a minimum at 126 °. The C12(d, p)C13 proton distribution shows minima in forward and backward directions and a maximum at 97 °. The ratio of C13(d, p)C14 over C12(d, p)C13 total cross-sections is equal to 8.7.
