Dear Vahan,
when you have some questions regarding a FLUKA command, the best thing is
generally to look it up in the manual.
Here is an excerpt from the description of USRBDX:
Note 2):
Angular distributions must be intended as distributions in
cos(theta), where theta is the angle between the particle
trajectory and the normal to the boundary at the point of crossing.
I suggest that you read the whole section about USRBDX: you may find other
useful informations
