The spectrum and term system of SVII
(2002) In Physica Scripta 66(2). p.140-149- Abstract
- The spectrum of six times ionized sulphur, S VII, has been investigated in the wavelength region 200-4000 Angstrom by means of the beam-foil and laser-produced plasma techniques. The analysis comprises 219 lines of which 105 are newly identified. The present work establishes 123 2s(2)2p(5)nl energy levels of which 66 are new. The level energies are determined with an internal consistency of better than 20 cm(-1). The observed level structure has been investigated by means of parametric calculations. The center-of-gravity ionization energy of the 2s(2)2p(5 2)P limit has been determined to 2 269 410 +/- 60 cm(-1). Of the identified 3s-3p and 3p-3d lines 27 are present in the solar coronal spectrum recorded by the SUMER instrument onboard the... (More)

Of the identified 3s-3p and 3p-3d lines 27 are present in the solar coronal spectrum recorded by the SUMER instrument onboard the SOHO satellite. The present work adds 2 new solar identifications and improved wavelengths of some other solar coronal lines. (Less)
