Inclusive electron scattering from an oxygen and argon jet target

An inclusive electron scattering experiment on 16 O and 40 Ar is presented. The ADONE electron storage ring, a clustered jet-target and a BGO calorimeter to detect electrons were used. Spectra were collected at beam energies from 0.5 up to 1.5 GeV and at laboratory scattering angles from 32 degrees to 83 degrees . The Coulomb sum rule integrated in the quasi-elastic peak at 570 and 800 MeV/c momentum transfer was measured in 16 O and our 40 Ar results were compared with the available data on 40 Ca.
