本文报道了1.27 ~ 1.66K温度范围内碱土金属离子Be ~+、Mg ~+、Ca ~+、Sr ~+和Ba ~+的迁移率测量结果。Be+的迁移率与Mg+相比表现出不同的行为，尽管这两种元素的性质相似。这可能表明，与Mg+的气泡状缺陷相比，Be+形成交替结构，可能是雪球。
Mobility measurements of alkali-earth ions Be+, Mg+, Ca+, Sr+ and Ba+ in the temperature range 1.27 to 1.66K are presented. The mobility of Be+ shows a different behavior in comparison to that of Mg+, although the properties of the two elements are similar. This may suggest that Be+ forms an alternate structure, perhaps a snowball, compared to the bubble like defect of Mg+.
