/* Experimental Method:
- Time-of-flight (To obtain outgoing neutron energy)
- Beam current integrated (Measurements were normalized by the
beam charge on the targets counted by the current digitizer,
model ORTEC-439, except for the case of the aluminum target,
which was slightly thinner than the proton range. In this case,
the beam charge was interpolated from runs before and after the
aluminum runs.)
