 TITLE=/ Characteristics of binary scission configurations in
         proton-induced fission of actinides /;
 PURPOSE=/ To clarify the correlation between mass yield
           distributions and scission configurations in low-energy
           proton-induced fission of actinides, and to elucidate how
           the bimodal properties vary as a function of fissioning
           nuclei in wide range of actinide fission /;

 /* Additional results shown but not compiled
    - Comparison with calculated values (Two-gaussian analysis. The
      elongation properties of nuclei at scission in a wide range of
      actinides fissions are studied. The results suggest that the
      compact and the elongated scission configurations in light
      actinides fission smoothly change to the scission properties of
      the symmetric and the asymetric modes in heavy actinides
      fission.)
