Assuming steady state conditions, the occupation of 9 levels of oxygen-like ions: Ne nI, Mg v, Si vii, S IX, and Ar xI have been computed as a function of electron density and temperature. The following physical processes have been considered: collisional excitations and spontaneous radiative de-exc

Steady state level density of 20 levels of boron-like ions, Mg viii and Si x, have been computed as a function of electron density and temperature. We have accounted for collisional and spontaneous radiative processes. Photo-excitation between the two levels of the ground term has also been consider
A comparison of Skylab S082A observations for several solar flares with calculations of the electron temperature sensitive emission line ratio R l = I(2s2p lp \_ 2s 2 1S)/i(2s2 p 3p1 \_ 2s 2 IS) = = 1(256.68 ~)/I(491.45 A,) in Be-like S xnI reveals good agreement between theory and experiment, which
