 Collision rate coefficient for an atomic transition

ID: collision-rate-coefficient-for-an-atomic-transition

f_{T} (v)

, the atomic transition rate coefficient is

q_{ij} (T) = \int σ_{ij} (v) v f_{T} (v) d v

. Its dimensions are volume per time, so the rate per target atom is

n_{e} q_{ij}

. Maxwellian detailed balance gives

q_{ji} = (g_{i} / g_{j}) e^{(E_{j} - E_{i}) / k T} q_{ij}

for

E_{j} > E_{i}
