EXPERIMENTAL DATA

For each reaction in the following files, there is a sequence of 30 dummy lines below the line describing the reaction. That data is tabulated in 4 columns: Energy, Energy-error, Cross-section, Cross-section-error. The references to this data with EXFOR numbers.

Individual excitation functions (O-Co)

Individual excitation functions (Zr)

Individual excitation functions (Au)
