Abstract

We present extreme ultraviolet spectra of Ag-like W27+ observed with an electron beam ion trap. In the spectra, the 4f7/2,5/2-5s electric octupole transitions are identified. Our theoretical investigation shows that the emission line intensity is strongly and specifically enhanced at the atomic number 74 by the anomalous behavior of the cascading contribution to 5s via 5p←5d.
