Measurements of the separated longitudinal structure function FL from hydrogen and deuterium targets at low Q2

NUCLEAR REACTIONS 1,2H(e, e'), E=2.24, 3.04, 4.41, 5.50 GeV; measured scattered electrons, differential σ(E, θ) using the high momentum spectrometer (HMS) and the short orbit spectrometer (SOS) at CEBAF-Thomas Jefferson National Accelerator (JLab) facility; deduced structure functions and longitudinal structure functions for protons and deuterons using Rosebluth separation technique, smaller longitudinal structure function and a smaller ratio of longitudinal to transverse cross section for deuteron than the proton, possible suppression of the gluonic distribution in nuclei. Comparison with parametrizations, previous experimental data, and theoretical predictions extrapolated to the beam energies investigated.
