[gate-users] pb with BGO material

[Bastien Gu é rin]

Dear All,

I have a problem when using the BGO material as it is defined in GATE. I
simulate a 511 kev photons beam on a BGO single block detector. The overall
spectra seem correct (photopeak @ 511 keV, Compton plateau with compton edge
@ 340 keV) but I have a peak (comparable to the compton edge) between the
compton edge and the photopeak. This clearly doesn't correspond to any
physical effect and something is wrong in this simulation. I check pretty
much everything but the mistake doesn't seem trivial to find.

Does one of you already encountered this problem?

Thanks a lot for your support!

BG
