Reactions induced by 150-350 keV deuterons on ¹²C and ¹³C

Thin self-supporting targets of natural C and enriched ¹³C were bombarded by deuterons, and energetically resolved particle groups were observed for the nuclear reactions ^12)C (d,p)¹³C g.s., ¹³C(d, p)¹⁴C g.s., ¹³C(d, α11^{B g.s., and 13}C(d, α)¹¹B^* (2.14 MeV). Excitation functions at θ_lab = 90° were measured for deuteron laboratory energies from 150 to 350 keV. Angular distributions, from θ_lab = 45° to 135°, were observed for both targets at 183.6 and 198.8 keV, plus 300.5 keV for ¹²C and 262.3 keV for ¹³C. Astrophysical S-factors determined from the excitation functions show almost no resonant structure. All of the angular distributions are anisotropic and only weakly energy dependent, with the differential cross section largest at forward angles for ¹³C(d, p)¹⁴C g.s. but largest at back-angles for ¹²C(d, p)¹³C g.s. and ¹³C(d,α)¹¹B g.s.
