Results are presented that were obtained by measuring a continuum in the inelastic scattering of 37-MeV deuterons on {sup 12}C, {sup 48}Ti, and {sup 58,64}Ni nuclei in the angular range 16{sup o} {<=} {theta} {<=} 61{sup o}. Broad excitation maxima are found for deuteron scattering angles in the range {theta} {<=} 21{sup o}. The region of a broad maximum includes giant resonances of target nuclei, whose levels are excited quite readily at E{sub d} = 37 MeV. Summation of the inelastic-scattering cross sections over all final states of the excited vertical bar nucleus and the use of completeness of the wave functions for these states make it possible to express the total cross section for inelastic (incoherent) deuteron scattering only in terms of the wave functions for the ground state of the target nucleus. The corresponding quasielastic-scattering amplitude is taken in the diffraction approximation. Nucleon correlations in the target nucleus are disregarded. Upon disregarding a small contribution of multiple quasielastic scattering at small scattering angles, the cross section for incoherent deuteron scattering is represented approximately as the product of known factors-the square of the absolute value of the amplitude for diffractive quasielastic scattering and the effective number of target nucleons scattering deuterons. The results of these calculations agree qualitatively with experimental data.
