The dataset was obtained from photonuclear reaction studies on 66Zn performed at the High Intensity Gamma-Ray Source at TUNL from Duke University, Durham, NC, USA. The data analysis and the results are discussed in the references given under "Related Resources". 

The datasets are given separately in the respective 'source_' files and given combined within in one file '66Zn_all_cross_sections.txt'.
The data contained in the file '66Zn_all_cross_sections.txt' are organized as follows.
