Strip 13 ampltiude spectra for the LiF and B samples. Also a picture of a simulation of what would be expected in a 20 um detector in terms of energy deposition for several reactions (assuming a thin sample).

- for B-10 n,alpha, the dominant reaction is n,alpha_1, so just seeing one peak makes sense

- for LiF we would expect 2 peaks, one around 1 MeV and one around 1.8. In the data it looks more like 1 peak while the lower energy "peak" is likely noise. My guess is that the sample is quie thick, which leads to a lower energy alphas, and a lower energy triton. As a consequence, the two peaks merge.

Conclusion:

- check the other LiF samples to see if we have any thinner samples

- try and rotate LI sample to confirm that the direction we are using now is the correct one.
