${{\boldsymbol \chi}_{{b2}}{(1P)}}$ $I^G(J^{PC})$ = $0^+(2^{+ +})$ J need confirmation.

Observed in radiative decay of the ${{\mathit \Upsilon}{(2S)}}$, therefore ${}^{C} = +$. Branching ratio requires E1 transition, M1 is strongly disfavored, therefore ${}^{P} = +$. $\mathit J = 2$ from SKWARNICKI 1987 .
