Abstract A distorted wave procedure is employed to correct the centrifugal sudden wave packet approximation, and the accurate results compared with the standard close coupling method for m-dependent integral cross sections for short- and long- range Ar+N2 potentials at E=O.O258eV are obtained only by using the second-order corrections to the CSWP wave function.

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.
