=== Carbon Captures ===
The plots below are neutrons captured by Carbon. Please note that making these plots required me to remove an energy cut I was using in the case of Hydrogen to ensure that the resulting energetic Hydrogen actually came from neutrons. I have manually checked a small portion of data and found that all excited Carbon came from a neutron parent. However, this was a very small portion of the data and cannot be assumed to represent the whole.
