%0 Journal Article %T The change of the collision parameters of ¡®O+ + N2 ¡ú NO+ + N¡¯ reaction according to geomagnetic activity days in the ionosphere %A Mehmet YA£¿AR %J - %D 2018 %X A plasma is a medium containing a large number of charged particle interactions. For this reason, it is common and appropriate to examine the plasma in terms of kinetic theory. In this context, the collision dynamics of the ¡®O+ + N2 ¡ú NO+ + N¡¯ reaction for geomagnetically quiet day (04/09/2017) and disturbed day (08/09/2017) were calculated for ionospheric altitudes with the help of kinetic theory. As a result of the calculation, it was seen that the mean free path values were less on the disturbed day, as expected. The total collisions number was seen to reach maximum at the height of hmF2 on both quiet and disturbed days, and the disturbed day values were greater. It was seen that the collision frequency decreased exponentially with altitude %K £¿arp£¿£¿ma frekans£¿ %K jeomanyetik f£¿rt£¿na %K iyonk¨¹re %U http://dergipark.org.tr/msufbd/issue/37908/438105
