Abstract
For the ions of the helium isoelectronic sequence (Z = 1 - 10) the resonanc e parameters (positions and widths) of the doubly excited Feshbach resonanc es of the (1,3)G(e) symmetries associated with the N = 3 and N = 4 threshol ds of the corresponding hydrogenlike ions have been calculated. The calcula tions have been carried out by using the complex rotation method, and highl y-correlated Hylleraas-type wave functions are used as basis functions.
