Abstract

Measurements are reported of the spherical tensor component t20 for 1.0-, 0.8-, and 0.4-GeV equivalent proton bombarding energies for elastic p-d scattering between 155̂°-175̂°. They are very close to zero in disagreement with the predictions of nucleon exchange models, including the Kerman-Kisslinger model with N* components in the deuteron wave function. The experiment was performed with a vector- and tensor-polarized deuteron beam scattered from a liquid hydrogen target.
