I have some problems with simulation program Monte Carlo MCNP:
I use this program to evaluate the energy lost by photons and electrons
in water. The source is a unidirectional high energy photons (
vertically, from up to down. I use the tallie F8.
During simulation, there is none electron production.
The output file there is no Compton scattering.
I write this code to command simulation:
SDEF POS=0 0 123 ERG=1.5 PAR=2 VEC=0 0 1 DIR=-1
MODE P E
PHYS:P 100 1 1
*F8: p,e 4 88i 93
The question is: do you see the mistake?
I thank you for your help.
