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#.

Isotope Threshold Energy (MeV) Incident Energy (MeV) Cross-section (mb) IE (MeV) CS (mb) IE (MeV) CS (mb) IE (MeV) CS (mb) IE (MeV) CS (mb)
[math]\displaystyle{ {12 \atop 6 }C_{6} }[/math] 18.72 N/A N/A
[math]\displaystyle{ {14 \atop 7 }N_{7} }[/math] 10.55 11 ~0.5
[math]\displaystyle{ {16 \atop 8 }O_{8} }[/math]
[math]\displaystyle{ {28 \atop 14 }Si_{14} }[/math]
[math]\displaystyle{ {208 \atop 82 }Pb_{126} }[/math]

Below is the previous data acquired for the cross sections.

Here is the literature for the C,N,O,Si,Pb([math]\displaystyle{ \gamma }[/math],n), cross sections. The table with all the data is on page 9 of the linked pdf file below.
