I'm trying to model the absorption of thermal neutrons by a gadolinium target. I'm using the following lines to define the physics list:
// Physics List
then in main ...
The program compiles fine but when I start the simulation I get:

*** G4Exception: Aborting execution ***
My environment variables are set and point to the correct directory:

What is wrong with my program/physics lists/environment variables? Thanks,
