Revised Analysis of Fe vii

Abstract New spectrograms of multiply ionized iron have been recorded and analyzed, targeting the Fe vii spectrum. As a result, several previously unknown spectral lines energy levels identified in this These new data analyzed together with all published laboratory astrophysical on The interpreted using parametric calculations Cowan codes. Radiative transition rates calculated work supplemented other constructing complete set recommended probabilities. ionization has redetermined fivefold improvement accuracy. Its value is 1,007,928(20) cm −1 , corresponding to 124.9671(25) eV.
