The study of 3s3p4 configuration in the P-Sequence, Co XIII - Ni XIV, by laser-produced plasmas

Abstract

Wavelengths from radiation of plasmas produced by a Nd:YAG/glass laser focused on target of Co and Ni have been recorded photographically in the region 240-600Å with a 3m normal incidence spectrograph. For this sequence (Co XIII and Ni XIV) we have identified 13 new lines belonging to the array 3s 2 3p 3 -3s3p 4 and derived 7 new levels for the 3s3p 4 configuration. The classification was established by comparison of the relative intensities for the lines along the isoelectronic sequence, extrapolation, and Hartree-Fock calculation.
