Isospin for photons?
See original GitHub issueThe isospin I of photons is returning <2. It’s bit confusing since isospin is related to strong interactions and W for example has no entry in the raw CSV file.
The <2 seems to refer to a “weak isospin” which has an unfortunate naming and the same symbol I. Wondering how this could be cleaned up a little bit? For the Julia implementation we try to fix the types and the photon is the only exception.
I guess you also had a discussion before you decided to put a <2 into the CSV I column? 😉
>>> from particle import Particle
>>> g = Particle.from_pdgid(22)
>>> g.I
'<2'
