Proton and \(^{12}\)C Neutron Yields

Source Data

These are all sourced from geant-val.

Differential Neutron Yields

The energy-differential neutron yields are shown below for each angle, beam energy and target material. NOTE: Due to the large amount of data, every third data point is shown for clarity of markers.

Integral Neutron Yields

The integral neutron yields are shown below. These were obtained by integrating using the trapezoidal rule. As through the function below:

NOTE: There seems to be disagreement with these and those presented in paper 1. It seems that similar results can be obtained by not using the trapezoidal rule but instead just summing over each data point. However, the trapezoidal rule should be used since the bin spacing is not homogeneous in the \(x\)-direction, so this must be clarified.
