An elemental carbon target enriched to 66% in ${\mathrm{C}}^{13}$ was bombarded with 14.8-Mev deuterons. Triton groups corresponding to the ground state, 4.43- and 7.65-Mev levels in ${\mathrm{C}}^{12}$ were magnetically analyzed and detected with photographic plates or a scintillation counter, at laboratory angles between 3 and 80 degrees. The angular distributions were found to be in good agreement with Butler pick-up theory, for $l=1\mathrm{}$. The values of the cross sections at the peak of the angular distributions are 24.3, 9.6 and 0.36 mb/sterad, respectively. These values are accurate within ±25%. The relative reduced widths connecting ${\mathrm{C}}^{13}$ with the ground state, 4.43- and 7.65-Mev levels of ${\mathrm{C}}^{12}$ are 1:0.76:0.039. The results are discussed.
