“…The same conclusions were reached in studies carried out at 40, 50 and 60 MeV [12,15,16]. In [16], the scattering of 3 He and the ( 3 He, α) reaction were studied for a number nuclei from 9 Be to 16 O at energies of 50 and 60 MeV. In particular, the angular distributions of α-particles from the 13 C( 3 He, α) reaction with a transition to the ground state of the 12 C nucleus were measured at the same energies as in the present work in the forward hemisphere region.…”

“…The ( 3 He, α) reaction has been studied to a lesser extent than the (p, d) and (d, t) reactions partly due to the fact that not all laboratories have been able to accelerate 3 He. Most of the early studies were carried out at energies below 20 MeV [1][2][3][4][5][6][7][8], and as a rule were limited to measurements of transitions to the low-lying states of nuclei. In addition, the analysis of data obtained within the framework of the direct mechanism of neutron pickup is greatly complicated by the significant contributions of other mechanisms such as the formation of a compound nucleus.…”

Cross sections for the 13C(3He, α)12C reaction were measured for 12C states up to excitation energies of about 20 MeV for 3He energies of 50 and 60 MeV. An analysis of the measured angular distributions was carried out using the Coupled Channels Born Approximation method under the assumption of a direct one-step mechanism of picking up a neutron from the 13C nucleus. In these calculations, the real parts of the implemented potentials were constructed within the framework of the double folding model. This analysis made it possible to extract the values of the spectroscopic factors for the 13C g.s. → 12C g.s. (12C*) + n configurations, which were found to be in reasonable agreement with theoretical predictions.

“…The 1 2level at 6.34 MeV is not observed in this experiment, implying a cross section less than 10 pbisr. In the low energy ( 5 , ~) experiment [6] this level is observed with about the same cross section as the 6.91 ( 5 / 2 + ) MeV state giving a spectroscopic factor that is at least one order of magnitude larger than in this experiment. 4.4 Concluding rtwarks Besides the pick-up of neutrons with I, = 1 the reaction 12C(p,d)11C is also observed to proceed by transitions with transferred angular momenta of 1,=2 and 1,=3.…”
