when i use text geometry construct(ExTGDetectorConstruction class),
the geometry is fine, but i suspect the material (u-235) not behave as it should be.
i beam On neutrons on sample of U-235,and it should make fission products,
but i get interactions resulting Pu-239,Am-239… particles.
i also change sample to Pu-239 ,and i got Pu-245,Am-245.
so there is no fission processes occurring…
