Abstract The above-threshold ionization of argon in an intense 70-fs, 400-nm linearly polarized laser pulse has been investigated by the velocity map imaging techniques, combined with an attosecond-resolution quantum wave packet dynamics method. There is a quantitative agreement in all dominant features between the experiment and the theory. Moreover, a peak-splitting phenomenon in the first energy peak has been observed at high pulse intensity. Further, through the theoretical analysis, an ac Stark splitting with evident resonant and nonresonant ionization pathways has been found to be the physical reason for the experimental observations.

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.
