Extraction of GM n from inclusive electron scattering on D, 4He

We use the relation between Structure Functions (SFs) of nuclei A and nucleons N in order to fomulate a criterion which isolates the QE part out of the total inclusive cross-section. From data points around the QEP we extract the reduced neutron magnetic form factor 〈α n = G M n/μ n G d〉. The latter shows an unexpected decrease up to Q 2 = 10GeV^2, the largest measured.
