Abstract
We calculate higher order contributions to spin-isospin quantities such as isovector axial vector coupling constant g A and the isovector magnetic moment μ l=1 in the chiral bag model. Quark contributions to those quantities are fully evaluated including vacuum polarization effects up to the order of Ω 1 in the cranking method for spin and isospin projection. It is confirmed that the higher order corrections have a sizable effect on g A at reasonable bag radii. The chiral bag model now has the correct limits of the MIT bag model at R → ∞ and the Skyrme model at R → 0.
