Quark-Antiquark states and their radiative transitions in terms of the spectral integral equation: Bottomonia

In the framework of the spectral integral equation, we consider the bb-bar states and their radiative transitions. We reconstruct the bb-bar interaction on the basis of data for the levels of the bottomonium states with J{sup PC} = 0{sup -+}, 1{sup --}, 0{sup ++}, 1{sup ++}, 2{sup ++} as well as the data for the radiative transitions {gamma} (3S) {sup {yields}} {sub {gamma}}{sub {chi}}{sub bJ}(2P) and {gamma}(2S) {sup {yields}} {sub {gamma}}{sub {chi}}{sub bJ}(1P) with J = 0, 1, 2. We calculate bottomonium levels with the radial quantum numbers n {
