Identification of Visible Lines in Pm-like W13+

Abstract

To provide spectroscopic data for W (Formula presented.), the present work is focused on the analysis of spectra observed in the visible range, using a compact electron beam ion trap (CoBIT). Line identification is done by using a collisional radiative model, along with sophisticated structure calculations from FAC and GRASP2018. Most of the identified lines belong to magnetic dipole (M1) transitions between the levels of the (Formula presented.) and (Formula presented.) configurations.
