Tortuous ways to the extraction of neutron observables from inclusive lepton scattering
Abstract
We analyze new JLAB data for inclusive electron scattering on various targets. Computed and measured total inclusive cross sections in the range 0.3 x 0.95 show on a logarithmic scale reasonable agreement for all targets. However, closer inspection of the Quasi-Elastic components bares serious discrepancies. EMC ratios which may contain less systematic errors fare the same. The above observations for the new data do not enable the extraction of the magnetic form factor (FF) GMn and the Structure Function (SFs) F2n of the neutron, although the application of exactly the same analysis to older data had been successful. We add to the above analysis older CLAS collaboration on F2D. Removing some scattered points, it appears possible to obtain the above mentioned neutron information. We compare our results with others from alternative sources. Particular attention is paid to the A=3 iso-doublet. Present data exist only for 3He, but the available input and charge symmetry also enable computations for 3H. Their average is the computed iso-scalar part and is compared with the empirical modification of 3He towards a fictitious A=3 iso-singlet.
