Abstract This paper reports that the transmission of O ions with energy of 150keV through capillaries in an uncoated AlO membrane was measured, and agreements with previously reported results in general angular distribution of the transmitted ions and the transmission fractions as a function of the tilt angle well fitted to Gaussian-like functions were observed. Due to using an uncoated capillary membrane, our is larger than that using a gold-coated one with a smaller value of , which suggests a larger equilibrium charge in our experiment. The observed special width variation with time and a larger width than that using a smaller were qualitatively explained by using mean-field classical transport theory based on a classical-trajectory Monte Carlo simulation.

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.
