[fluka-discuss]: alpha and tritium production from Li-6 (pwxs)

Dear Alfredo,

I am contacting you regarding a potential small issue I have encountered
in FLUKA.
I have created an input file designed for calculating the response
function in Lithium Iodide within a Bonner sphere using the RESNUCLEI
card. When I use multigroup transport, the number of tritium and alpha
nuclei generated is the same, as expected physically from the neutron
absorption reaction with Li-6.
However, when I use the pointwise cross-sections, the number of tritium
and alpha nuclei produced is different.
Am I making an error in setting up the input, or is there some process I
might be overlooking?

For better understanding, I am attaching the input file and the _sum.lis
files obtained in both cases.

Thank you in advance for your response.

Best regards,
