E(1+)/M(1+) AND S-1+/M(1+) FROM AN ANALYSIS OF P(E,E'P)PI(0) IN THE REGION OF THE DELTA(1232) RESONANCE AT Q(2)=3.2 (GEV/C)(2)

We have analyzed exclusive p(e, e'p)pi(0) data to determine the electromagnetic and scalar transition multipoles in the mass region of-the Delta(1232) at the highest Q(2) value where data exist. The ratio of the electric quadrupole and the magnetic dipole transition moments is determined to be E(1+)/M(1+) = 0.06 +/- 0.02 +/- 0.03, and for the scalar quadrupole transition we find S-1+/M(1+) = 0.07 +/- 0.02 +/- 0.03. The results rule out that perturbative QCD governs the dynamics of the gamma(upsilon)ph transition at such Q(2). They are more consistent with predictions of relativistic extensions of the nonrelativistic constituent quark model.
