Inelastic scattering of vector polarized deuterons near E d = 20 MeV has been measured for a series of target nuclei ranging from the sd shell to 232 Th. Isoscalar transition rates deduced from a collective-model analysis are found to be in agreement with the corresponding electromagnetic quantities for the quadrupole and octupole excitations of T = 0 nuclei and of 208 Pb. For the quadrupole excitation in 144 Sm, 152 Sm, 154 Sm, and 232 Th about 20% smaller values are obtained, which imply a larger proton than neutron deformation for these nuclei.

The 2~--excitation of deformed nuclei by tensor polarized deuterons provides an alignment of both nuclei and thus a means to study specifically the quadrupole-quadrupole interaction between both nuclei. The tensor analyzing power A=(O) has been measured for the elastic and inelastic scattering on 24Mg and ZsSi. The coupled channel analysis including a deformed tensor potential reveals a clear signature of the quadrupole-quadrupole part of the nuclear projectile-target interaction.

The elastic scattering of vector and tensor polarized deuterons near 20 MeV has been analyzed in terms of the phenomenological optical potential including a complex tensor term of TR-type. In comparison with folding potentials we find a strong reduction of the real part of the TR-potential with increasing mass number, the contribution of coupling to vibrational excitations is discussed.Nuclear Reactions: 4He, 160, a6Ar, 4~ 6SCu, 144Sm, 2~ T21(0), optical potential analysis, deduced: TR tensor potentials.
