Puzzling Isotonic Odd-Even Staggering of Charge Radii in Deformed Rare Earth Nuclei
Endre Takacs, Hunter Staiger, Steven A. Blundell +16
The nuclear charge radius is a fundamental observable that encodes key aspects of nuclear structure, deformation, and pairing. Isotonic (constant neutron number) systematics in the…

Extreme Ultraviolet Spectroscopy of Highly Charged Lu and Yb Ions for Nuclear Charge Radius Determination
Hunter Staiger, Endre Takacs, Steven A. Blundell +16
We report a high-precision determination of the natural-abundance-averaged nuclear charge-radius difference between Yb and Lu using extreme ultraviolet (EUV) spectroscopy of highly…

A laboratory plasma experiment for X-ray astronomy using a compact electron beam ion trap (EBIT)
Yuki Amano, Leo Hirata, Moto Togawa +11
We present the basic performance and experimental results of an electron beam ion trap (JAXA-EBIT), newly introduced to the Japanese astronomical community. Accurate atomic data ar…
