Title: Tortuous Ways to the Extraction of Neutron Observables
     from Inclusive Lepton Scattering

Abstract:
New data on inclusive cross sections of unpolarized electrons in 
several targets JLab exp. E03-102) have been analyzed on their 
potential to extract $G_M^n$ and $F_2^n$. We have used exactly 
the same tools as in the analysis of older data, which produced 
at the time the desired information from different kinematics. 
When plotted on a a log scale, calculations for total cross 
sections agree with data on the inelastic side of the QE. Since 
there inelastic processes (NI)dominate we trust their calculated 
values.

We analyzed the QE parts, once as [data-NI], then as an expression 
in terms of form factors. Ideally those should agree. Except for 
a few points those two disagree, frequently very much so. This 
seems to point at incompatibility of the old and new data. For the 
same reason one cannot extract $F_2^n$.

We then analyzed the CLAS collaboration data on $F_2^{p,D}$ and 
could obtain the above $n$ properties.  

We discuss the above problem and general status.
