| dc.description.abstract | The helicity-dependent recoil proton polarizations P[superscript '][subscript x] and P[superscript ′][subscript z] as well as the helicity-independent component P[subscript y] have been measured in the p([→ over e],e[superscript ′][→ over p])π[superscript 0] reaction at four-momentum transfer Q[superscript 2]≃0.1 GeV[superscript 2], center-of-mass proton emission angle θ[superscript *][subscript p]≃90°, and invariant mass W≃1440 MeV. This first precise measurement of double-polarization observables in the energy domain of the Roper resonance P[subscript 11](1440) by exploiting recoil polarimetry has allowed for the extraction of its scalar electroexcitation amplitude at an unprecedentedly low value of Q[superscript 2], establishing a powerful instrument for probing the interplay of quark and meson degrees of freedom in the nucleon. | en_US |
