用MeV量级4 HeH+在超薄无衬碳膜中的库仑爆炸 ,获得高频离子源产生4 HeH+核间距的实测值为 0 .0 94±0 .0 0 3nm .发现4 HeH+与H+2 ,H+3 不一样 ,其核间距大小和离子源种类及离子源参数有密切关系 ,并从4 HeH+的形成机理与形成条件 ,解释了高频离子源和双等离子源产生4 HeH+核间距不同的原因
Coulomb explosion with a MeV magnitude of 4 HeH + in an ultrathin linerless carbon membrane resulted in a measured value of 4 HeH + nuclei at a high frequency ion source of 0.094 ± 0.30 nm. It was found that 4 HeH + and H + 2 , H + 3 is not the same, the size of its nuclear and ion source species and ion source parameters are closely related, and from the 4 HeH + formation mechanism and formation conditions, explained the high-frequency ion source and dual plasma source 4 HeH nuclear spacing is different s reason
