Attempts are made to unify gravity with the other three fundamental forces of nature. As
suggested by higher dimensional models, this unification may require space and time …

Optical spectra of Fe-like Mo 16+ and Mn-like Mo 17+ ions were measured using the newly
developed low-energy electron-beam ion trap at Fudan University. The observed emission …

To provide spectroscopic data for lowly charged tungsten ions relevant to fusion research,
this work focuses on the W 8+ ion. Six visible spectra lines from W 8+ in the range of 420 …

Experiments on an electron-beam ion trap (EBIT) and calculations using flexible atomic
code (FAC) are carried out to study the charge-state evolution from W 5+ to W 7+. The W 7+ …

To provide relevant atomic data for fusion research, a collisional-radiative model (CRM)
simulation is conducted using the Flexible Atomic Code (FAC) to identify the 10 visible lines …

The wavelength and transition rates of W 43+-W 45+ ions in the 40-140 Å region have been
calculated by the relativistic configuration interaction method with the implementation of the …

We present the first measurements of visible radiation from W 10+. The ions are produced
and confined in an electron-beam ion trap (EBIT) at Shanghai EBIT Laboratory, and the …

Abstract The Flexible Atomic Code (FAC) is developed to extend the computational scale
based on the Relativistic Configuration Interaction (RCI) in the theoretical study of W 9+ …

We present a new investigation of unidentified emission lines in 350–660 nm from W 11+ at
a compact electron-beam ion trap in Shanghai. To help the line identification, transition …

To extend the research on the atomic structure of tungsten ions with an open 4f-shell, we
conducted an investigation into the M1 transitions originating from the ground configuration …
