Abstract The (e, 2e) triple differential cross sections of Neon and neonic ions (Z=11-14) 2s orbital were calculated using distorted-wave Born approximation in coplanar asymmetric geometry. The calculated results showed that, with the increase of nuclear charge number Z, the amplitude of triple differential cross sections decreased. The angle difference between binary peak position and the angle of momentum transfer gradually increased with the increase of nuclear charge Z, and a new structure appeared at ejected angle 90o<θ2<120o. Three kinds of collision processes were proposed to illustrate the formation mechanism of such collision peaks.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
