“…These structures have been mainly attributed to the exchange of one or a few valence nucleons reproducing the elastic channel and interfering with the "direct" elastic scattering [1]. Similar to the case of elastic scattering, strong oscillations have been observed [2][3][4][5] at scattering angles around 0 = n/2 in the angular distributions of transfer reactions between composite particles with identical cores. These oscillations have been interpreted as due to two interfering transfer processes leading to the same exit channel [3][4][5][6][7][8].…”

Abstract. The general symmetry properties of the T-matrix due to the exchange of identical cores in nuclear reactions between composite particles are given. For the case of direct transfer reactions an explicit expression for the cross section is derived in the distorted wave Born approximation. In this model the cross section is the coherent sum of two indistinguishable transfer processes. The relative phase between the corresponding transfer amplitudes is obtained from the Pauli principle and depends on the signs of the spectroscopic amplitudes which may, therefore, be determined experimentally.

Residual interaction to be used in the no-recoil DWBA for treating the heavy-ion induced transfer reaction is derived on the basis of the folding model for the potentials. Improvement of the interaction potential produces change in the magnitude but not in the angular dependence of the cross section. Contribution of the Coulomb interaction must be included in treating the transfer process of a charged particle.

“…On peut donc supposer l'existence d'un niveau au voisinage de 29,4 MeV, mais il n'y a aucune indication quant à sa largeur et à son spin. L'étude de 11 B(p, a)8Be à des énergies incidentes correspondant à la zone d'excitation [25][26][27][28][29][30] MeV dans le 2C [46] montre que cette réaction procède essentiellement par mécanisme direct, mais inhibé par un fort mismatch angulaire, et que, d'autre part, la partie arrière de la distribution angulaire a un comportement résonnant avec l'énergie incidente.…”

La réaction 9Be(3He, α) a été étudiée entre 4 et 10 MeV. L'analyse des courbes d'excitation et des distributions angulaires met en évidence la prépondérance d'un mécanisme de noyau composé en dessous de 7 MeV et un mécanisme de pick-up d'un neutron j = 3/2 aux énergies incidentes supérieures à 7 MeV. La compilation des résultats acquis dans le domaine d'excitation du 12C et en particulier sur les résonances géantes multipolaires du 12C permet d'interpréter la structure résonnante observée à 29,5 MeV par l'excitation de composantes isoscalaires (3-, 4+) de ces résonances
