NaI's efficiency
In the definition of relative efficiency for HpGe we divide the counts of each peak for the line’s intensity (%) and fit the relation between efficiency and Energy with the following function (vedere quella del germanio). With the NaI obviously is not possible (because of bad resolution) . Since each peak is formed by several lines, we divided the counts of each gaussian for the sum of intensity of all lines that form the peak . The method is fundamentally wrong because it doesn’t considerer the presence of Compton scattering in the peak (as Mattia suggested), but it may be interesting for a qualitative study , as we can see in imageXXX:

mi autocommento:
1) ammetto che gli errori sono parecchio tirati a caso (ma proprio tanto) e che i punti che rompevano le balle li ho silurati, quindi l'attendibilità del fit è un po' deprimente
2)ricordiamoci di chiedere a tabrelli se sta cosa si può fare che preferisco essere insultata PRIMA dell'esame...
