How to estimate intensity of dielectronic satellite lines
Intensity of a dielectronic satellite line can be calculated with
a following equation:
where IH is the ionization potential of hydrogen,
Te is electron temperature,
g0 is the statistical weight of initial parent state
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
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.
