In the present study, the excitation of small helium clusters belong to different point groups has been studied using the configuration interaction singles (CIS) method. The stationary points, located on their excited potential energy hypersurfaces, were found. Also, a new systematic approach was proposed in order to facilitate the geometry optimization process of the software. In this approach, the cuttings from the different directions on the excited potential surfaces were created. In the other part of this work, the most probable relaxation pathways of the excited structures corresponding to the saddle points were explored. The dissociation and structural deformation of the clusters were observed in the explored relaxation pathways. During the non-adiabatic relaxation pathways, the structures corresponding to the conical intersection points were determined. Based on these studies, it was observed that some stable point groups which were stable in the ground electronic state also exist in the excited states. For an instance, the helium trimer (He 3 ) with the C 2v and D ?h point groups exists in the excited electronic states at this level of theory.
