Re: Question neutron reflection (Simone)

From: Simone <Simone>

hello,

I am going on with the tests to understand why neutrons don't behave like expected

I found out that the interaction probability of neutrons depends on the distance from which they are shoot. if i shoot 10000 neutrons (100 eV) from 1 mm to a 40 um thick Bi slab i get ~250 interactions, but increasing the distance the number of hadronelastic interactions increases as well. shooting neutrons from 1 meter causes ALL the neutrons to interact on the slab surface.

this can't obviously make sense. this weird behaviour seems to be present at different energies (100 eV, 1MeV, 1 GeV), and to affect only neutrons (i made tests with e-, protons and alpha but they don't seem to be affected from distance, as expected)

I think you should make some test too, i think this could be a bug

thanks

simone
