Investigation of the nucleon’s excited states has always become an important research topic because of the rich information they provide. Since their first observation, dating back about 70 years, the investigation of their various parameters contributed both to the development of the quark model and a better understanding of the QCD as the theory of strong interaction. Their investigation still has importance. The research conducted on the nucleon excited states is helpful to probe the missing resonances predicted by the quark model but not observed yet. With this motivation, we study the low lying nucleon resonance with ##IMG## [http://ej.iop.org/images/0954-3899/47/9/095005/gab9d37ieqn3.gif] {$I\left({J}^{P}\right)=\frac{1}{2}\left({\frac{3}{2}}^{-}\right)$} and its corresponding orbital and radial excitations with ##IMG## [http://ej.iop.org/images/0954-3899/47/9/0950...] {$I\left({J}^{P}\right)=\frac{1}{2}\left({\frac{3}{2}}^{+}\right)$}

由于其提供的丰富信息,对核子激发态的研究一直成为重要的研究课题。自从他们的大约70年来的首次观察以来,对它们的各种参数的研究既促进了夸克模型的发展,也使人们对作为强相互作用理论的QCD有了更好的理解。他们的调查仍然很重要。对核子激发态进行的研究有助于探究夸克模型所预测但尚未观察到的缺失共振。以此动机,我们使用## IMG ## [http://ej.iop.org/images/0954-3899/47/9/095005/gab9d37ieqn3.gif] {$ I \ left( {J} ^ {P} \ right)= \ frac {1} {2} \ left({\ frac {3} {2}} ^ {-} \ right)$}及其对应的#轨道和径向激发#IMG ## [http://ej.iop。
