摘要： 用激光蒸发方法产生大量的FexPy+,通过对其形成过程和稳定性的研究,确定了主要的气相反应方程式为Pz+Fex+→FexPy++Pz-y.结合理论计算获得的团簇离子电子占有态的结果,解释了团簇离子质谱中奇偶性产生的原因。

Abstract: The formation and stability of FexPy+cluster ion produced by laser ablation were investigated.The gas-phase reaction equation in the formation of these cluster ions is Pz+Fex+→FexPy++Pz-y. And the odd-even variation related to the number of Patom in mass spectrum was explained with the calculation of the electronic occupied state in the cluster ions in which the electronic structure of transition metal dominates the bonding in cluster ions, and the higher ionization energy of even cluster ions results in removing easily electrons from the single electron occupied states of cluster ions.

Key words: Cluster, Laser ablation, Odd-even variation
