| dc.description | The splittings $1D-1P, 1F-1P, 2D-2P$ are shown to be the most convenient characteristics to determine the vector coupling in IR region. In background perturbation theory the splitting $Δ=1D -1P$ appears to be in agreement with $Δ(\exp) =261.1 \pm 2.2$ MeV only for large freezing value, $α_{crit} \cong 0.60$, which corresponds to $Λ_{\bar{MS}} (2$-loop, $n_f=5)\cong 240$ MeV $(α_s(M_Z) =0.1193(2)$. The masses $M_{cog} (1F)=10362\pm 3$ MeV and $M_{cog} (2D) =10452\pm 4 $ MeV are predicted. | |
