Report of Referee A (LC8573 Zhu,H)
--------------------------------------------------------------------

This manuscript constitutes a very important contribution to the
interesting issue of form factors of the nucleons. Recent
precision experiments on cw-electron accelerators have
tremendously improved the data bases for the proton as well as
for the neutron. The new measurements with polarisation
contitute a major step in quality in particular as they permit
direct determination of the ratio Ge/Gm, which has low
experimental uncertainties and which is almost model independent
apart from FSI corrections. To corroborate the new findings on
the neutron, which are about a factor 2 larger than the
previously assumed values, it is an important contribution to
show that consistent values are obtained with different targets
and reactions, and thus different experimental conditions.

I strongly recommend a speedy publication of these results.

The authors, however, should improve the manuscript on the
following points:

1) Abstract:  make clear what is the issue about `first':

   .. report a measurement of the neutron el. ff via ...
      using for the first time a solid polarized target.

2) discussion of corrections:

   Is the normalisation of the MC one single number for all
   materials?

3) explain filled square in fig. 3

4) A discussion is missing about p=5.6 of the Galster parametri-
   sation. This value is asummed in the analysis whithout ex-
   planation and evaluation (chi-square). If the authors claim
   that their value sets a new constraint the have to evaluate the
   data base.  The Gen analysis by Herberg EPJA(1999) and Grabmayr
   PRL(2001) show different fit parameters.

5) update the references of preprints e.g. ref 23 appeared in PRC

Report of Referee B (LC8573 Zhu,H)
--------------------------------------------------------------------

This paper presents an important result on the structure of the
neutron that has wide interest for both nuclear and particle
physics. It represents a new and technically challenging method to
extract the very small electric form factor of the neutron through
the use of polarized electrons and polarized neutrons. The
analysis of the data is quite thorough and well done, all the
impotant aspects that may mask the correct extraction have been
included.

The measurement of the neutrons electric charge distribution has
been an outstanding challenge for many years and only recently has
technical advance premitted these recent experiments.

It is unfortunate that this group was not able to also make a
series of momentum transfer dependent measurements which would
have been very valuable. However this is an important result that
vindicates an new experimental technique and has promise for
futher results.

I recommend publication ini PRL.
