Resumen:
A capillary discharge tube was used to record the Ar spectrum in the region of 330?4400Å. We analyzed a set of109 lines of ArV, with 10 of them being classified for thefirst time. Part of these newly identified lines(six in total)corresponds to electric dipole transitions in the visible and ultraviolet regions of the spectrum. We calculatedweighted transition rates(gA) for all experimentally observed lines and the corresponding lifetimes using arelativistic Hartree?Fock method with configuration interaction. The equations were modified to consider corepolarization(CP)effects. A study on the Si isoelectronic sequence found that considering CP effects is essential forthe correct description of the ArVstructure.
