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
| Isotope | Threshold Energy (MeV) | Incident Energy (MeV) | Cross-section (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.
