Cross Sections (taken from JENDL-4.0)
     Table of cross sections, Cm-248.
     Figures of cross sections, Cm-248:  type-1:  type-2:  type-3.
       type-1: total, elastic and inelastic scattering, capture and fision cross sections
       type-2: same as type-1 but cross sections are averaged in 70 energy group intervals
       type-3: threshold reaction cross sections
