Abstract
The decay constants and the radiative decay widths of {eta}{sub b}(nS) and {eta}{sub c}(nS) are computed within a semirelativistic quark model, using a potential found through the AdS/QCD correspondence. For {eta}{sub c}, the results are in agreement with experimental data, while in the case of {eta}{sub c}{sup '} a discrepancy is found and the possible reasons are discussed.
