摘要：

Ions ejected from a liquid metal ion source of an Li-Mg (10 atom %) alloy have been investigated by using a magnetic mass analyzer. In addition to singly charged homonuclear Li(n)+ (n less-than-or-equal-to 9) and Mg(n)+ (n less-than-or-equal-to 4) and heteronculear Mg(m)Li(n)+ (m, n less-than-or-equal-to 2) clusters, doubly charged diatomic and triatomic Mg clusters are observed. Discussion is focused on the observability and the formation mechanism of the doubly charged small Mg clusters. A postionization process is suggested for the formation of the doubly charged clusters.
