Clusterization and strong coupled-channels effects in deuteron interaction with $^9$Be nuclei

International audienceAngular distributions of protons, deuterons, tritons and alpha particles emitted in the d + 9Be reaction at E lab = 19.5 and 35.0 MeV have been measured. The elastic scattering channel is analysed in the framework of both the optical model and the coupled-channel approach. The interaction potential of the d + 9Be system is calculated in the framework of the Double-Folding model using the α + α + n three-body wave function of the 9Be nucleus. The (d, p) and (d, t) one-nucleon-transfer reactions are analysed within the coupled-reaction-channel approach. The spectroscopic amplitudes for the different nuclear cluster configurations are calculated. Differential cross sections for the reaction channel 9Be()7Li are calculated including all possible reaction mechanisms within the coupled-reaction-channel method. Corresponding contributions to the cross sections are analysed
