Possible issue with new neutron librairies about water

[horvathd (Dávid Horváth)]

Hi Jean-Baptiste,

Currently the thermal scattering laws are only available in the JEFF-3.3 package, and it is needed for the water bound hydrogen.

You still can use JEFF-4.0 similarly to the solution in

LOW-PWXS using ENDF

Dear @Mihaela_Parvu the thermal scattering laws we have available, only exist in the JEFF-3.3. You can still select ENDF as a library for every material with LOW-PWXS, but you would need to ask FLUKA to load the HYDROGEN S(a,b) from JEFF-3.3, like [image]

Cheers,
David
