Penning traps, renowned for their unparalleled precision in determining fundamental properties such as mass and magnetic moments, are cornerstone instruments in modern physics. The…
Prediction of Nuclear Clock Transitions Frequency Difference between Th and Th via \textit{ab-initio} Self-Consistent Field Theory
Ran Si, Chaofan Shi, Nan Xue +4
The isotope is a promising candidate for nuclear clocks, with its transition frequency influenced by electron-induced nuclear frequency shifts. This effect is com…
Probing Nuclear Excitation by Electron Capture in an Electron Beam Ion Trap with Non-destructive Isomer Detection via Precision Mass Spectrometry
Bingsheng Tu, Nan Xue, Jialin Liu +10
Nuclear excitation by electron capture (NEEC) is an important nuclear excitation mechanism which still lacks conclusive experimental verification. This is primarily attributed to s…
