Abstract: In the framework of the distorted-wave approximation, an approach for calculating the amplitude of the deuteron-like particle break-up in the field of a heavy target nucleus at over-barrier energies is developed. The proposed approach is based on the approximate solution of the Schrodinger equation and can be used in calculating the amplitudes for other nuclear reactions. A method for accounting the nonzero interaction radius of the deuteron-like particle components has been also developed and the comparison of the calculated and measured deuteron breakup cross sections by ⁴⁰Ca nuclei is made. It was shown that taking into account the internal structure of the deuteron significantly affects the behavior of the calculated observables.

Keywords: distorted-wave approximation, break-up reactions, interaction potential, over-barrier energies.
