they record all interactions' positions.

My simple guess is that you did a plotting mistake. I ran 3d4 primaries
with your input and your mgdraw [by the way in the statement
if(kpart(ip).eq.8 .and. kpart(ip).gt.hikin) nocount=ip
the second condition does not make any sense (hikin=0d0 always). In fact
it does not affect at all the assignment, but I think you had in mind
tki(ip) instead - why? -.]
The resulting distribution is attached. I let you interpret it more
deeply, but at a glance it does not look unreasonable (you can of
course improve the statistics).
Cheers
Francesco
