1s-photoionization of atomic neon is accompanied by outer shell
excitation and ionization. The simultaneous K and L electron ionization,
which represents 16% of the single K electron ionization, produces Ne
IV states by KL-LLL Auger decays. In astrophysical situations where a
thin plasma is exposed to energetic photons, these Ne IV excited states
give rise to soft X-ray lines with intensities of the same order of
magnitude as the main Ne III lines resulting from the 1s2s(2)2p(6) K-LL
Auger decay. Experimental and theoretical data on Auger and radiative
rates, allow us to estimate some Ne II, Ne III and Ne IV relative soft
X-ray line intensities (350-600 Angstrom)
