Περίληψη:

We present a measurement of the induced proton polarization P-n in pi(0)
electroproduction on the proton around the Delta resonance. The
measurement was made at a central invariant mass and a squared
four-momentum transfer of W=1231 MeV and Q(2)=0.126 GeV2/c(2),
respectively. We measured a large induced polarization, P-n = -0.397 +/-
0.055 +/- 0.009. The data suggest that the scalar background is larger
than expected from a recent effective Hamiltonian model.
