Title: Longitudinal-Transverse Separations of Deep-Inelastic Structure Functions at Low Q{sup 2} for Hydrogen and Deuterium

Abstract

We report on a study of the longitudinal to transverse cross section ratio, R={sigma}{sub L}/{sigma}{sub T}, at low values of x and Q{sup 2}, as determined from inclusive inelastic electron-hydrogen and electron-deuterium scattering data from Jefferson Laboratory Hall C spanning the four-momentum transfer range 0.06<Q{sup 2}<2.8 GeV{sup 2}. Even at the lowest values of Q{sup 2}, R remains nearly constant and does not disappear with decreasing Q{sup 2}, as might be expected. We find a nearly identical behavior for hydrogen and deuterium.
