摘要：

In a recent letter Bachau, Roncin and Harel have proposed an ingenious method based on the PCI effect to obtain stabilization of certain classes of autoionizing states during ion-atom collisions. In this comment we argue that although the effect as such is possible we find several difficulties with its application to cases for which stabilization has been observed.
