Magic Number Cluster Ion Mn + 5
1996
Magic number cluster ion mn-5(+) and abundant mn/o cluster ions have been formed by 532nm laser ablation of mnco3 solid sample with time-of-flight mass spectroscopy detection. the experimental results show that mn-5(+) was formed in the cooler dilute tail region of the plume produced by laser ablation, while mn/o cluster ions were mainly formed in the hotter dense preceding portion of the plume, they all were produced by postablation cluster growth in the ablation plume. pentagonal with d-5h symmetry is the possible structure of mn-5(+), which is supported by our ab initio calculation.
