Cross Sections (taken from JENDL-4.0)
Table of cross sections, Sr-90.
Figures of cross sections, Sr-90: 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
