I am confused as to what is considered the official version of Fluka. Today, I received an email saying that a new version of Fluka 2020 is available. On the other hand, I can find suggestions that the official version is V4 at CERN.
I have recently pointed out that these codes give different results for the (g,n) cross section of Ra-226.
Fluka is a powerful code and I appreciate the effort that has gone into developing and maintaining it. However, as a user it would be good to know what the developers recommend as the “best” version.
Thanks, Carl Ross
