How to estimate intensity of dielectronic satellite lines
Intensity of a dielectronic satellite line can be calculated with
a following equation:
(photons cm3s-1),
where IH is the ionization potential of hydrogen,
Te is electron temperature,
g0 is the statistical weight of initial parent state
i0,
EiS is energy level of autoionizing state i
measured from initial state i0,
and Qd(i,j) is intensity factor obtained as follows
with gi statistical weight of autoionizing state i,
Aa autoionization rate,
and Ar radiative transition probability:
.
For the most cases, Aa is much larger than
Ar and then approximately Qd
becomes
.
In the data set of this database,
Qd and the wavelength are included as defualt, and
Es (EiS in the above equation) is
included in some cases.
