Description

Dear FLUKA experts,

I want to use the cross-section data of the element at a temperature of approximately 550 K. However, when I use the LOW-MAT card, I find that I can only link it to the data at temperatures of 87 K and 296 K. How can I define the temperature I want?I have found that the LOW-PWXS card can also be used to define temperature, but the transport mode I want to adopt is multigroup transport.

Best regards,
Liu

Low energy neutron cross sections at arbitrary temperatures can indeed be obtained with LOW-PWXS for pointwise treatment only, which is the more advantageous mode and is to be preferred.
