“…D-state effects in the α-particles are very sensitive to the short-range behaviour of the nucleon-nucleon tensor force because the two deuterons must be in close proximity in order to be tightly bound in the α-particle. The analysing power A xx of the (d, α) reaction is very sensitive to D-state contributions in the α-particle wavefunction and therefore the A xx of (d, α) reaction data can be used to test realistic α-particle wavefunctions (Crosson et al . 1992).…”

Cross sections of two-nucleon pickup reactions in the 13 C+d system, i.e. 13 C(d, α0) 11 B and 13 C(d, α1) 11 B * reactions have been measured for 180-350 keV deuterons. The angular distributions were measured in steps of 20 keV at 14 angles ranging from 30 • to 164 • , while the excitation functions were measured at 90 • in steps of 10 keV. The excitation functions of 13 C(d, α0) 11 B and 13 C(d, α1) 11 B * reactions with 5 • 167 and 3 • 307 MeV Q-values, respectively, exhibit smooth variations of cross section with energy. The angular distribution of 13 C(d, α0) 11 B reaction is asymmetric. With decreasing deuteron energy, the degree of asymmetry increases and below 220 keV deuteron energy the angular distribution is backward-peaked. This indicates a dominating contribution from the direct reaction in this channel below 220 keV deuteron energy. The angular distribution of 13 C(d, α1) 11 B * reactions are highly symmetric about 90 • , indicating a dominating compound nucleus contribution over this energy range. The trends of angular distribution of 13 C(d, α0) 11 B and 13 C(d, α1) 11 B * are consistent with the results of Putt (1971) at higher deuteron energies.

“…The 13 C(d, p) 14 C cross section had already been measured at 410-810 keV deuteron energies by Putt (1971), who also reported DWBA calculations made using the zero-range approximation. However, there is now a need to repeat these cross section calculations using an improved DWBA technique that incorporates the finite-range approximation and includes D-state contributions in the nuclear wavefunctions (Crosson et al . 1992(Crosson et al .…”

Cross sections for deuteron stripping from the 13 C nucleus have been measured for 200-350 keV deuterons. The excitation functions of the 13 C(d, p) 14 C reaction were measured at 30 • , 66 • , 110 • , 128 • , 146 • and 164 • , while the angular distributions of the 13 C(d, p) 14 C reaction were measured at deuteron energies of 200, 230, 250, 270, 290, 310, 335 and 350 keV. The excitation functions of the 13 C(d, p) 14 C reaction show a smooth variation of the cross section with energy. The angular distributions of the 13 C(d, p) 14 C reaction are highly asymmetric and are forward-peaked. The asymmetric shape of the angular distribution of the 13 C(d, p) 14 C reaction indicates a dominating contribution from the direct reaction in this channel. The trend in the angular distributions of the 13 C(d, p) 14 C reaction is consistent with published results at higher deuteron energies (Putt 1971).
