用7 keV的正离子轰击产生了锰团簇离子Mnk ~+（k = 60），用双聚焦质谱仪进行了分析。在k =5，14，16，29，34，45和54处发现强度的不连续变化。这些幻数中的大多数与在方舟+中观察到的幻数一致或仅相差一个。Mn ~（k+）和方舟~（k+）幻数的相似性表明，带电Mn团簇与带电Ar团簇的成键性质相似，团簇中心的正离子与周围中性原子之间的极化力是主要的结合力.
Manganese cluster ions Mnk+ (k≲60) have been produced by 7 keV Xe ion bombardment and analyzed by a double-focusing mass spectrometer. Discontinuous variations of intensity are found atk=5, 14, 16, 29, 34, 45 and 54. Most of these magic numbers coincide with or differ by only one from those observed in Ark+. The similarity in magic numbers between Mnk+ and Ark+ indicates that the bonding nature in the charged Mn clusters is similar to that in the charged Ar clusters; The polarization force between a positive ion in the center of a cluster and surrounding neutral atoms is dominant binding force.
