Query: Nucleon-nucleus scattering as a test of shell structure of some light
  mass exotic nuclei   Shell model wave functions have been used to form microscopic g-folding
optical potentials with which elastic scattering data from 8He, 10,11C, and
18,20,22O scattering on hydrogen has been analyzed. Those potentials, the
effective two-nucleon interaction used in their formation, and the shell model
details, then have been used in distorted wave approximation calculations of
differential cross sections from inelastic scattering to the first excited
states of five of those radioactive ions.
