摘要：
In this paper, we investigated the transition form factors of nucleon resonances, in an analytical approach. Employing an improved hypercentral constituent quark model, we obtained analytical eigenfunctions which have been used to calculate the transverse and longitudinal helicity amplitudes for nucleon resonances. We compared the evaluated observables with experimental data and it has been shown that the present model provides a good description of the available data. (C) 2020 Elsevier B.V.
