Cross Sections of C,N,O,Si,Pb
Here is the updated data for the C,N,O,Si,Pb([math]\displaystyle{ \gamma }[/math],n), cross sections. All the data here was taken from "Hand book on photonuclear data for applications Cross-sections and spectra" October 2000 Edition.
For the Energy and cross-section if the threshold is above 15 MeV then N/A will be placed due to maximum incident energy = 15 MeV
The cross-sections will be listed at each integer value of incident energy after the threshold up to 15 MeV under the columns IE#. Cross-sections are listed under the CS colums.
