Calculation of theηandη′masses in the bag model

Abstract
The annihilation contribution to the masses of the JPC=0+ isoscalars is calculated in the bag model. The resultant mass shift for the η is large and positive. For αs=1.15 we obtain mη=0.53 GeV and mη=0.965 GeV, leading to a good description of pseudoscalar masses within the model.
