Comparative analysis of (p, d), (d, t) and (3He, α) reactions on13C nucleus

Study of highly excited states in 16O with 3He+13C reactions at low energies

“…From the experimental point of view, very few data are available in the literature. In particular, they have been mainly obtained at moderately-high energies, where more direct reaction mechanisms are typically favoured as opposed to the formation of a compound nucleus [34][35][36][37]. In particular, Kellogg and Zurmuhle [34] studied the reaction at 12, 15 and 18 MeV, proposing a direct pick-up mechanism to describe the trend of angular distributions.…”

Study of the 13C(3He, α)12C reaction at energies of 50 and 60 MeV

“…Only a few previous studies have been devoted to the 13 C( 3 He, α) 12 C reaction [1,2,4,[9][10][11][12][13][14][15][16][17] (see also [18] and the references therein). Data for energies below 10 MeV [1,2] showed that the angular distributions for transitions to the ground and low-lying excited (4.44 MeV (2 + ) and 7.65 MeV (0 + )) states of 12 C cannot be fully explained within the framework of direct pick-up of one neutron from p 1/2 and p 3/2 shells using the standard distorted wave method; an acceptable description can be achieved only by including the contributions from compound nucleus formation.…”

“…At 3 He energies of above 10 MeV, the mechanism of neutron pick-up in the ( 3 He, α) reaction becomes more pronounced [17]. Thus, in [14], where studies were carried out in the energy range of 16-23 MeV, calculations using the distorted wave method and assuming direct neutron transfer could describe the experimental data in the forward hemisphere for strongly excited states, but were unable explain the entire dataset, especially at large angles, unless the exchange mechanisms with the transfer of the heavy cluster ( 9 Be) were included.…”
