Dear Experts,
I am trying to get Wigner small d matrix elements in ROOT. I couldn’t find any functions to extract them in recent versions of ROOT. I found a comparatively older @mzimbres package in this post, Wigner d-functions - #3 by mzimbres to extract such elements. However, this package is also not running. Are they implemented in ROOT framework as a function or something to get them quickly?
In Python, I found sympy package, Wigner Symbols - SymPy 1.12 documentation , where the elements can be accessed easily.
Can someone guide me to extract such d elements in ROOT or in PyROOT (preferably).
_ROOT Version: ROOT 6.26/04
Platform: Not Provided
Compiler: Not Provided
