Dear FLUKA experts,

I need to study probability of muon elastic scattering with large angle
(>20 mrad) in lead.

I have a setup of muon beam passing though lead target.
I want to observe muon elastic scattering events, using USRDRAW user
routine. I removed all the binary output from mgdraw.f template file, and
put simple text output to standart log unit, like this:
       ENTRY USDRAW ( ICODE, MREG, XSCO, YSCO, ZSCO )
       WRITE(*,*)"usr=",ICODE," trk=",JTRACK
       RETURN

Also I put
MULSOPT 0.0 0.0 0.0 3.0 1.0 99999999.GLOBHAD
as recommended in the manual, to substitute MCS with single scattering
everywhere.
In the output I get lots of delta-ray production e.t.c., but I do not get
any elastic scatterin("usr= 100") in my output.

Is single scattering supposed to trigger USRDRAW? Or is there any
other way I could get information about single scattering events?

Thank you in advance,

Andrey Sheshukov.
