you can intercept electrons at their generation in the USDRAW entry of the
mgdraw user routine. There, ICODE refers to the generation process (I
would say mainly 103 - delta ray generation - in your case) and XSCO,
YSCO, ZSCO give the generation point. Through (GENSTK) you can
search among the np secondaries for electrons (kpart(ip)=3) and get their
direction and energy/momentum. You may want to suitably set the threshold
for delta ray production (DELTARAY card).
