• Druyvesteyn distribution
• non-Maxwellian distribution
• averaged collision strength
• Carbon Pi ion 133.53 nm

Non-Maxwellian distribution has been found in laboratory and space plasma in recent years. In this paper, averaged collision strengths of Carbon Pi ion 133.53 nm are calculated for Druyvesteyn distribution for the non-Maxwellian distribution, when temperatures vary from 10(4.4) K to 10(6.0) K. Results indicate that significant differences between the averaged collision strengths occur for the Druyvesteyn distribution and the Maxwellian distribution, furthermore, for the Maxwellian distribution and the Druyvesteyn distribution with any characterizing parameter x, the averaged collision strengths increase with increasing temperature, and the averaged collision strengths are close to those of the Maxwellian distribution when the characterizing parameter x is close to x = 1. This calculation is significant for non-Maxwellian plasma.
