摘要：
Doubly excited KLL states were populated by triple electron capture in collisions of fast C6+ ions with Ar atoms. Measurements of the Auger electron emission at zero degrees with respect to the beam direction were used to determine the absolute single differential cross sections (SDCS) for the triple electron capture to all autoionizing KLL states. In addition, independent particle model was utilized for the calculation of cross sections for individual L-J states of populated intrashells. The agreement of theory and experiment promoted conclusions about the role of projectile screening and electron-clectron correlation effects in multiple electron capture in fast, highly charged ion-atom collisions.
