实验用光学多道分析系统(OMA)测量了He2+和Ne,Ar碰撞过程中的发射光谱,结果表明,这些碰撞体系存在着三种激发过程:双电子俘获激发过程、单电子俘获激发过程和直接激发过程。

2023年7月26日 · 从原子核对电子的吸引能力来看，He的 核电荷数 是2，而Ne的是10，是He的5倍，其他4个稀有气体元素的核电荷数递增倍数都不超过2。而Ne只比He多1个电子层，原子核对电子的吸引力比He要强，更不容易失去电子。

6 天之前 · The dimer 4 He 20 Ne is detected roughly 10 times more often than the isotope-substituted dimer 4 He 22 Ne due to the difference in the natural abundance of the isotopes 20 Ne and 22 Ne. ... Ground state potential energy curves for He2, Ne2, Ar2, He-Ne, He-Ar, and Ne-Ar: A coupled-cluster study. Cybulski, Slawomir M.; Toczylowski, Rafal R.

The emission spectra in collision process between He2+ and Ne, Ar have been measured using optical methods, by Optical Multichannel Analysis. System. The experimental results demonstrate that there are three channels of excitation in these collision systems: double-electron capture into excited states, single-electron capture into excited ...

1989年5月1日 · Emission cross sections of HeI, HeII, NeI, NeII, and ArI, ArII have been obtained. Some comparisons of emission cross sections between He 2+ + Ne and He 2+ + Ar are given.

2025年2月25日 · 本研究表明，低能He2+、O6+离子与Ne原子碰撞中的态分辨电荷转移现象受到多种因素的影响。 其中，Ne原子的电子态对电荷转移的机制具有重要影响。 此外，离子的能量、速度以及离子的种类等因素也会影响电荷转移的概率和机制。

1975年8月1日 · Experimental studies of collisions of He 2+ ions with Ne, Ar, and Kr atoms have been carried out at laboratory kinetic energies in the range 8 ⩽ E1 ⩽ 10 eV. For each collision pair, relative differential cross sections for elastic scattering, and for the formation of He + by single charge transfer [e.g., He 2+ + R = He + + (R +) *] were measured.

2018年2月7日 · He2这两个He原子在1s轨道上本来就已经有一对自旋相反的电子, 如果要组成分子, 成键轨道与反键轨道都恰好被占据, 两者能量就被抵消, BO=0, 不能成键. 而He2+由于失去了一个电子, 两个电子在成键轨道，一个电子在反键轨道, BO=1/2, 故能存在.这里形成的Sigma键也叫 三 ...

本研究通过对He2+与He以及Ne8+与O2、N2和CH4之间的碰撞进行实验研究，探究了单电子捕获（SEC）和双电子捕获（DEC）的总绝对交叉截面。研究范围分别为3.5-50keV/u和2.8-40keV/u。通过对实验系统的系统误差和数据评估的深入分析，SEC交叉截面的实验结果误差小于9%。

Experimental studies of collisions of He2+ ions with Ne, Ar, and Kr atoms have been carried out at laboratory kinetic energies in the range 8 ⩽ E1 ⩽ 10 eV. For each collision pair, relative differential cross sections for elastic scattering, and for the formation of He+ by single charge transfer [e.g., He2+ + R = He+ + (R+)*] were measured.
