Study Of The 3p4 Configuration In Four-times Ionized Argon, Ar V

The atomic emission spectrum of four-times ionized argon, Ar v, has been observed in the vacuum ultraviolet (VUV) region. The 3s3p3-3p4 transition array has been studied for this ion This is the first study of the 3s3p3-3p4 transition array which occurs in the Si I isoelectronic sequence. Seventeen new lines that belong to this transition array were classified. All five levels of the 3p4 configuration were determined. The configurations are interpreted by fitting the theoretical energy expressions to the observed energy levels using a least-square-fitting technique The identifications are supported by Hartree-Fock relativistic calculations.292460496053Biémont, E., (1986) J.
