摘要：

Using a coincident energy gain spectrosopy, experimental evidence is given of the direct stabilization of two electrons following a double-electron capture process at keV energies. At variance with indirect stabilization, this mechanism does not require a transfer to highly asymmetric Rydberg series. Three examples are given in which both direct and indirect stabilization mechanisms are found to coexist.
