  The E12-14-012 experiment performed at Jefferson Lab Hall A has collected
inclusive electron-scattering data for different targets at the kinematics
corresponding to beam energy 2.222 GeV and scattering angle 15.54 deg. Here we
present a comprehensive analysis of the collected data and compare the
double-differential cross sections for inclusive scattering of electrons,
extracted using solid targets (aluminum, carbon, and titanium) and a closed
argon-gas cell. The data extend over broad range of energy transfer, where
quasielastic interaction, Delta-resonance excitation, and inelastic scattering
yield contributions to the cross section. The double-differential cross
sections are reported with high precision (~3%) for all targets over the
covered kinematic range.
