Dear experts,
I want to check neutron resonances like ex-5 with Cd foil.
For this I use lead target in moderator (polyethylene)
then I look at N flux using the hole in the concrete wall.
I use W foil and NEW-DEFA
In the attachment there is the picture of N flux into
W-foil and output from the foil.
There is NO ANY resonance here.
So, my questions :
- I use TUNGSTEN here, it is known that natural W consists from
4-5 stable isotopes, which have neutron resonancies
TUNGSTEN in FLUKA is natural ? 4 isotopes ?
- if TUNGSTEN is not natural - then how I can create this material ?
I cannot find any example, how to compose materials from isotopes -
because I need names , which I do not know
could you please give me this example ?
- what else I must do to see the picture as I see for Cd in ex-5
with neutron resonance ?
thank you
Vladimir Babintsev
