We decided to change the target to 197Au, 2 mg/cm2 (pos 6) in order to check how the gamma spectra look like.

We obtained a very clean gamma spectrum compared to the one collected with Pb target. We concluded that the Pb target is probably contaminated and it's also probably the effect of the frame size - Au target is mounted on a frame with a bigger hole than Pb, means that we could have seen also the reactions on the frame (supported by the hole2_test run with the frame with empty hole).

The rates are low now, however, the spectra look cleaner and we got rid of many lines, originatiing from the reactions.

We decided to run with Au target over the night and collect some statistics.
