Ardan,
Not identical, but definitely similar. The scattering cross-sections
are different for X-rays and electrons. Electron scattering is also
very sensitive to bonding (electron cloud radius) whereas X-ray
scattering is proportional to Z with a simpler form-factor.
However, to the extent that C = N = O and hydrogen scatters less for
electrons and X-rays, they are similar.
