Dear all,

scoring the energy in an air-filled cavity in a waterphantom irradiated
by a 1.25 MeV photon beam I habe encountered an interesting problem:
Using the USRBIN-card one can score the energy either in the region
(called "chamber") or use the R-Phi-Z geometry that exactly matches my
region called "chamber". So since I am scoring the energy in the same
region (in different ways concerning my USRBIN) I should get the same
results. However the results are different: 4.64538e-10 GeV pm
0.0290214% for the region-scoring and 5.15530840E-10 GeV pm 3.25998449%
for the R-Phi-Z-scoring.
Do you have an idea why this is so? Especially concerning the statistics
that are quite different?
In the attachment you can find my input-file.

Best regards,
Kilian
