Dear Colleagues, we have some problems with using of the thermal neutron scattering models.
We are considering the project Hadr04 and we introduced following changes in it:
1. We removed Oxygen from the water. Now it consists of only Hydrogen ("TS_H_of_Water").
2. We changed the Hadr04.cc. Now it runs vis1.mac without any dialogs.
3. We changed the PrimaryGeneratorAction.cc in order to set the initial energy of emitted neutron to 4 eV.
Now we expect to see how the S(a,b) model works. But unfortunately we don't see any single scattering process. The neutron either is immediately captured by the atoms or it leaves the mother volume. The output file shows the results of such experiment.
It seems we wrongly activated the thermal scattering process. But we have no idea how to make it right. Can anybody help us with this issue?
vis1.mac contains the following strings:
