Magnetic dipole transitions between fine-or hyperfine-structure splitting in the np 2 3 P
ground term have been proposed to develop ultraprecise atomic clocks (https://link. aps …

The lifetime of the galliumlike Mo 11+ ion 4 s 2 4 p P 3/2 2 metastable level was measured at
an electron-beam ion trap. The lifetime was inferred from the temporal behavior of its …

Long-lived ionic quantum states known as metastable electronic states in highly charged
ions (HCIs) are of great interest in fundamental physics. Especially, it generates transitions …

The spectroscopic investigation of optical spectra of Ca-like Br 15+, Kr 16+, Zr 20+, and Rh
25+ ions at an electron beam ion trap was presented. In the region of 200-700 nm, ten …

In this work, we report a spectroscopy measurement of Ru 21+ to Ru 24+ ions in the optical
region using a low energy electron beam ion trap. Twelve lines were observed. The …

Through the examination of energy level crossings among the fine-structure manifolds of the
(n= 4− 5) d 6 and (n= 4− 5) d 8 configurations in a number of highly charged ions (HCIs), we …

This study presents both experimental and theoretical analysis of the 4d 2 D 5/2→ 2 D 3/2
magnetic dipole transition in Rb-like ions. Spectral lines of Xe 17+, La 20+ and Pr 22+ ions …

The visible spectrum of Mo $^{15+} $ ions was measured using a high-temperature
superconducting electron-beam ion trap at the Shanghai EBIT Laboratory, with an electron …

An experimental measurement of the lifetime of 3d 9 2 D 3/2 metastable level in Mo 15+ is
reported in this work. The Mo 15+ ions are produced and trapped in an electron beam ion …

This work reported the investigation of optical spectra of Rh-like Xe9+ and Ru-like Xe10+
ions at a low-energy electron beam ion trap. The line from 4 d 9 2D3/2–2D5/2 M 1 transition …
