Measurement of R = σ L / σ T and the separated longitudinal and transverse structure functions in the nucleon-resonance region

We report on a detailed study of longitudinal strength in the nucleon resonance region, presenting new results from inclusive electron-proton cross sections measured at Jefferson Lab Hall C in the four-momentum transfer range 0.2
