摘要：

The double-differential coincidence cross section for the reaction 1H(e,ep)0 has been measured at Q2=0.1(GeV/c)2 in a range in the invariant mass of 214 MeV above threshold. From the angular dependence of the data values of the pion s-wave multipoles E0+ and L0+ have been extracted. The results are compared to predictions from chiral perturbation theory and models based on an effective Lagrangian. None of the models is able to describe both the E0+ and the L0+ multipoles. © 1995 The American Physical Society.
