Abstract
The dominant one-photon radiative transitions of the charmonium ground and orbitally excited states have been studied within an analytic confinement model. In addition to two fixed basic model parameters (\({{m}_{c}}\) and the confinement scale \(\lambda \)), we introduced only one adjustable parameter common to six charmonium states: \({{\eta }_{c}}\), \(J{\text{/}}\psi \), \({{\chi }_{{c0}}}\), \({{\chi }_{{c1}}}\), \({{h}_{c}}\) and \({{\chi }_{{c2}}}\) to parameterize the quark distribution inside the hadron. Our estimates are in good agreement with the latest data.
