Abstract: The angular distributions of protons, deuterons, tritons, and alpha particles emitted in the d+ $^{9}$Be reaction at energies $E_{lab}(d)$ = 19.5 and 35.0 MeV were measured. The elastic scattering analysis is carried out in the framework of the optical model and the coupled channel method. The interaction potential of the d + $^{9}$Be system was calculated using the double folding model using the three-body wave function α + α + n for the $^{9}$Be nucleus. The analysis of the single-nucleon transfer reaction (d, p) and (d, t) in the framework of the coupled channel method is carried out. Spectroscopic amplitudes are calculated for various configurations of nuclear clusters.
