In this study, the transition helicity amplitudes from the proton ground state to the N(1440)1/2⁺, N(1520)3/2^–, and Δ(1620)1/2^– resonances (γvpN* electrocouplings) were determined from the analysis of nine independent onefold differential π⁺π^–p electroproduction cross sections off a proton target, taken with CLAS at photon virtualities 0.5GeV² < Q² < 1.5 GeV². The phenomenological reaction model employed for separation of the resonant and nonresonant contributions to this exclusive channel was further developed.
