Some natural elements are not easily comparable as they are sometimes not present as such in a given evaluation. For example, Silicon is given only as Natural in JEF-2.2 and its isotopes are given in JEFF-3.1.1.
To compare total cross-section of SiNat in JEF-2.2 versus that of JEFF-3.1.1 you need to perform the following steps.
Open the nuclide chart of Nubase 2003 to retrieve the abundances of Si-28, Si-29 and Si-30.
Perform an ENDF search with the following parameters:
“Open results” in a new Renderer window.
Right-click on a node to select the menu “Computations>New...”.
Enter the following equation:
You can then plot the JEFF-3.1.1 computed cross-section and the JEF-2.2 one.
