+to reconstruct an event, we need first and second interaction sites, and scattering angle
+1. assume initial energy is known as 0.661MeV. we only need to know the energy deposited in the first cell; thus we can select 1-->3 or 1-->1 event pairs. the scattering angle is:
+
+ cos(\theta) = 1 - E_d1 * mc^2 / (0.661 * (0.661-E_d1))
+
+2. if the initial energy is unknown, we select 1-->3 event pairs, i.e., photon deposits all its energt in second cell. the scattering angle is:
+
+ cos(\theta) = 1 - E_d1 * mc^2 / ((E_d1+E_d2) * E_d2)
+
+
+while histNo < max:
+ get pulses with same history number
+ if number of pulse != 2:
+ go to next hist number
+ else:
+ parse line
+ sort pulses by erg_par_in
+ if interaction of second pulse is not 3:
+ go to next hist number
+ calculate scattering angle
+ get interaction sites from dum1 file, based on history number and cell number:
+ select all interactions with the same history number
+ sort by cell number
+ pick up the one with the mathching cell number and max energy of all
+
+how do we know whether the photon deposits all its energy in the second interaction?
+Simulation shows that there are many multiple scattering events.
