Atomic data and spectral line intensities for the nitrogen isoelectronic sequence (Ar XII through Kr XXX)

The electron impact collision strengths and the spontaneous radiative decay rates are presented for the following ions of the Ne isoelectronic sequence: Si V, Ar IX, Ti XIII, Fe XVII, Ge XXIII and Kr XXVII. Data are given for the 27 levels that belong to four different configurations (2s22p6, 2s22p53s, 2s22p53p, and 2s22p53d). By use of the atomic data calculations of the above-mentioned ions, the atomic data for all the ions with 14 ⩽ Z ⩽ 36 have been interpolated. Energy levels and level populations are presented for all the even-Z ions with 14 ⩽ Z ⩽ 36 (Si V, S VII, Ar IX, Ca XI, Ti XIII, Cr XV, Fe XVII, Ni XIX, Zn XXI, Ge XXIII, Se XXV, and Kr XXVII). The level populations are given for the three electron densities 1013, 1014, and 1015 cm−3. Spectral line intensities are also presented for all transitions with intensities within two orders of magnitude of the most intense line in each ion.
