Hi again,

I've since done some more checking. I have a framework I've used in the past that uses a slightly modified version of the DMXPhysicsList. I tried two things:

1) Replace the DMXPhysicsList in that framework with the Shielding list. The anomalous n,alpha interactions showed up (>100 / 500 events with 1MeV neutrons in a block of copper).

2) Replace the Shielding list in my main framework wth the DMX list. The n,alpha interaction didn't show up in 10k events.

I think it's pretty clear that this is an issue with either Shielding or one of the processes that it registers, at least in 4.9.4.p02. I'm not really in a position to test agains 4.9.5 right now.

Cheers, ~Ben
