We present preliminary results on an experimental study of the nuclear modification of the longitudinal (σ_L) and transverse (σ_T) structure functions of nucleons bound in nuclear targets. The origin of these modifications (commonly referred as as the EMC effect) is not fully understood. Our measurements of R= σ_L/σ_T for nuclei (R_A) and for deuterium (RD) indicate that nuclear modifications of the structure functions of bound nucleons are different for the longitudinal and transverse structure functions, and that contrary to expectation from several theoretical models, R_A < R_D.
