İyonkürede jeomanyetik aktivite günlerine göre ‘O+ + N2 → NO+ + N’ reaksiyonunun çarpışma parametrelerinin değişimi

Öz

Bir plazma çok sayıda yüklü parçacık etkileşimlerini içeren bir ortamdır. Bu nedenle plazmayı kinetik teori açısından incelemek yaygın ve uygundur. Bu bağlamda jeomanyetik olarak sakin gün (04/09/2017) ve tedirgin gün (08/09/2017) için ‘O⁺ + N₂ → NO⁺ + N’ reaksiyonuna ait çarpışma dinamikleri kinetik teori yardımıyla iyonküresel yüksekliler için hesaplandı. Hesaplama sonucunda ortalama serbest yol değerlerinin beklenildiği gibi tedirgin günde daha düşük olduğu görüldü. Toplam çarpışma sayısının ise hem sakin hem de tedirgin günde hmF2 yüksekliklerinde maksimuma ulaştığı ve tedirgin gün değerlerinin daha büyük olduğu belirlendi. Çarpışma frekansının ise üstel olarak azaldığı görüldü.

The change of the collision parameters of ‘O+ + N2 → NO+ + N’ reaction according to geomagnetic activity days in the ionosphere

Öz

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 → 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.
