New distorted-wave impulse approximation calculation for inelastic scattering of deuterons at intermediate energies with the sudden approximation approach

Abstract

We perform a distorted-wave impulse approximation calculation of inelastic scattering of deuterons by nuclei using effective interactions in the framework of the sudden approximation at ${E}_{d}=400$ MeV. Cross sections and spin observables are expressed in terms of amplitudes for the corresponding nucleon-nucleus scattering. The calculation is examined for the excitation of ${}^{12}\mathrm{C}$ to the ${2}^{+}$ (2.44 MeV), ${3}^{\ensuremath{-}}$ (9.64 MeV), and ${1}^{+}$ (12.71 MeV) states and is found to give a reasonable description for most of the observables. Some discrepancies are found for the transition leading to the ${1}^{+}$ state, suggesting the limitation of the applicability of the effective interaction. Contributions of the deuteron D state are studied. Relations between the deuteron-nucleus and proton-nucleus scattering observables are found and are studied against existing data.
