Popis:	Double electron transfer processes for the system Fe{sup 17+}+He have been studied utilizing high-resolution Auger electron spectroscopy. A thorough analysis of the experimental conditions (single collision condition and metastable fraction content at the incident ion beam and their influence) has been performed, leading to the following conclusions. The double capture leads to the preferential population of 2{ital p}{sup 5}5{ital l}8{ital l}{sup {prime}} configurations sharing their decay between Auger processes and radiative cascade transitions. The observed sodiumlike {open_quote}{open_quote}quartet{close_quote}{close_quote} and {open_quote}{open_quote}doublet{close_quote}{close_quote} states result from cascade contributions from higher-lying levels. Tentative mechanisms for the production of the quartet states are suggested using a spin-flip model. {copyright} {ital 1996 The American Physical Society.}
