The Feshbach projection method and the generalized saddle-point technique have been used to obtain energies of [sup 4,2][ital P[ital e]] and [sup 4,2][ital D[ital o]] Feshbach resonances in He[sup [minus]], Li, and Be[sup +]. The results from both methods confirm each other. Positions and Auger energies of 31 resonances (3 in He[sup [minus]], 14 in Li, and 14 in Be[sup +]) lying between the 2 [sup 1][ital P[ital o]] and 3 [sup 3][ital P[ital o]] thresholds are given. These data can serve as a basis for identification of those resonances in future experiments. Some suggestions for such experiments are made.
