Hi, ALL,
I have checked different variants (and manuals also) about
neutron resonances, They absent in the output for
TUNGSTEN (W), And as I can see - for all other materials also.
May be somebody knows answers for the following questions :
1) I tryed to compose material from 182_W and 183_W isotopes,
but I think, that something is wrong...
Could you please check my test.inp - file in the atachment ?
2) does anybody know the simple method to simulate some
known resonances for the given material ?
(where are there data with cross-section vs E ?)
3) is there open and free method to fit (reconstruct)
this simulated or real resonances ?
thanks,
Vladimir Babintsev
