The angular distributions of the elastic and inelastic deuteron scattering on /sup 9/Be, /sup 11/B, and /sup 12/C were measured with the Heidelb erg MP tandem Van de Graaff accelerator. At a constantly maintained relative energy of 14.5 MeV of the bombarding projectile--target system, the laboratory incident energies were 17.745, 17.155, and 16.939 MeV. The particle separation was done by the electronic pulse multiplication method. The deflected 11.8-MeV deuteron beam of the Heidelberg cyclotron was used for measurement of the target thickness. The shields of the counter telescope were measured with the 0.05-MeV alpha particles of a /sup 212/Pb source. The elastic scattering was analyzed with the optical model with use of various parameter terms. The optical parameters determined agree partially with the parameter terms found at 11.8 MeV. The variation of the parameters from nucleus to nucleus is ascribed to the fraction of the compound elastic scattering. Some angulation distributions of the inelastically scattered deuterons can be described with the DWBA method according to the collective model and the microscopic theory. The BETA /sub L/ values and the strength of the nucleon--nucleon interaction respectively determined therefrom agree well with the values determined by other methods. An attempt was made to describe the strongly excited states of /sup 11/B with the excited core model and with the Nilsson model. For the Kurath theory, in which the excited states of the nuclei of the lp/sub 3/2 shell have a pure lp-shell structure, the 1o/sub 3/2 yields 1p/sub 1/2 transition calculations were made for one excited state of the /sup 9/Be, /sup 11/Be, and /sup 1 2/C nuclei, (13 figures, 8 tables) (tr-auth)
