New Measurements of the European Muon Collaboration Effect in Very Light Nuclei

New Jefferson Lab data are presented on the nuclear dependence of the inclusive cross section from ²H, ³He, ⁴He, ⁹Be and ¹²C for $0.3<x<0.9$, Q²≈3--6 GeV². These data represent the first measurement of the EMC effect for ³He at large x and a significant improvement for ⁴He. The data do not support previous A-dependent or density-dependent fits to the EMC effect and suggest that the nuclear dependence of the quark distributions may depend on the local nuclear environment.
