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.
