“…We refer to this phenomenon as cluster polarization. One expects cluster polarization to play a role in reactions which involve light nuclei with small separation energy such as the deuteron, 6 Li, 7 Li, and so on. One also expects the effects to be more pronounced at small energies of the colliding nuclei, due to the longer interaction time intervals.…”

“…They are connected with the lowest binary channels 4 He + 3 He and 6 Li + p which define the main properties of the bound and some resonance states of 7 Be. Only 1.5 MeV is necessary to split the 6 Li nucleus in 4 He and d. To disintegrate the 3 He nucleus in a deuteron and a proton the total energy of 3 He has to exceed 5.5 MeV. To split the 4 He nucleus into a proton and 3 H already more than 20 MeV is needed.…”

“…The first, introduced by Tang et al [1][2][3][4][5][6], considers internal monopole excitations to describe the polarization. The second, introduced by the Kiev-Antwerp collaboration [7][8][9][10][11][12][13][14][15], is based on collective monopole and quadrupole polarizations of the compound nucleus.…”

“…In the reaction 6 Li(p, 3 He) 4 He one structureless subsystem, the proton, and three cluster subsystems 6 Li, 4 He and 3 He are involved. They are connected with the lowest binary channels 4 He + 3 He and 6 Li + p which define the main properties of the bound and some resonance states of 7 Be.…”

A microscopic model for three-cluster configurations in light nuclei is presented. It uses an expansion in terms of Faddeev components for which the dynamic equations are derived. The model is designed to investigate binary channel processes in a compound system. Gaussian and oscillator bases are used to expand the wave function and to represent appropriate boundary conditions. We study the effect of cluster polarization on ground and resonance states of 7 Be, and on the astrophysical S-factor of the reaction 6 Li(p, 3 He) 4 He.

Abstract. The three-nucleon system is studied within the multi-configuration resonating-group method. The model space is spanned by p + d, p + d', and their associated pseudo-inelastic configurations. The results show that, at lower energies less than about 15 MeV, the calculated p + d differential scattering and total reaction cross sections agree well with experiment, suggesting that the use of pseudo-inelastic configurations can yield an adequate description of deuteron direct-breakup processes. At higher energies, the agreement is less satisfactory, owing mainly to the adoption of a relatively small number of pseudo-inelastic configurations in our formulation. The p + d inter-cluster interactions are found to be appreciably odd-even L-dependent and are characteristically different in channel spin S = 23 and 89 states. Specific distortion effects of the deuteron cluster are also studied. For relative orbital angular momentum L = 0, these effects turn out to be small in the S = 23 state but are quite large in the S = 89 state.
