Revisiting the 12C(d, p)13C reaction cross section using condensed gas targets

Abstract We have measured the differential cross section for the 12 C(d, p) 13 C nuclear reaction at a laboratory scattering angle of 150° for incident deuteron energies near 972 keV. The measurements have been calibrated by comparison with the well known cross section for the 16 O(d, P 1 ) 17 O reaction at the same energy (972 keV) and angle, corresponding to the peak of a broad resonance in the latter reaction cross section. The technique utilized condensed targets of gases containing both carbon and oxygen atoms, viz. CO, CO 2 , and CH 3 OH. The three values thus obtained for the 12 C(d, p) 13 C laboratory cross section at 972 keV are in excellent agreement (± 2%). A mean value of 27.8 ± 1.1 mb sr −1 is recommended. We conclude that, for CO adsorbed on the Pt(100) and Pt(111) surfaces at 185 K, the reported saturation coverages were stoichiometric.
