Inner-shell excitation energies and autoionization rates for C-, N-, O-, and F-like ions with Z=6-54

Absolute energies of the autoionizing states 1s2s(2)2p(n) [LSJ] with n = 3- 6, 1s2s2p(n) [LSJ] with n = 4-6 and 1s2p(n) [LSJ] with n = 5-6, and non-aut oionizing states 1s(2)2s2p(n) [LSJ] with n = 2-6, 1s(2)2s2p(n) [LSJ] with n = 3-6, and 1s(2)2p(n) [LSJ] with n = 4-6 were calculated for ions with a n uclear charge Z = 6-54 by using the 1/Z perturbation theory method. These s tates were considered as the states with one or few holes in the Ne-like co re state 1s(2)2s(2)2p(6). Relativistic corrections were taken into account in the frame of the Breit operators. The autoionization rates for the above -mentioned autoionizing states and ions were computed as well and are shown in graphic forms as Z-dependences. These new atomic data represent an impo rtant material, which can be used in different areas of atomic and plasma p hysics involving the study of multiply-charged ions.
