摘要

我们描述了一种测定高Z 核素绝对核半径的新技术。利用精确的原子结构理论计算和对高电荷离子的极紫外跃迁的精确测量，这种方法可以根据众所周知的邻近元素的核半径来精确测定绝对核电荷半径。这种方法适用于没有稳定同位素的元素，其准确性可与目前的方法（电子散射和μ介子 X 射线光谱法）相媲美。

Absolute nuclear charge radius by Na-like spectral line separation in high-Z elements

We describe a novel technique to determine absolute nuclear radii of high-Z nuclides. Utilizing accurate theoretical atomic structure calculations together with precise measurements of extreme ultraviolet transitions in highly charged ions this method allows for precise determinations of absolute nuclear charge radii based upon the well-known nuclear radii of their neighboring elements. This method can work for elements without stable isotopes, and its accuracy may be competitive with current methods (electron scattering and muonic x-ray spectroscopy).

期刊介绍： Published twice-monthly (24 issues per year), Journal of Physics B: Atomic, Molecular and Optical Physics covers the study of atoms, ions, molecules and clusters, and their structure and interactions with particles, photons or fields. The journal also publishes articles dealing with those aspects of spectroscopy, quantum optics and non-linear optics, laser physics, astrophysics, plasma physics, chemical physics, optical cooling and trapping and other investigations where the objects of study are the elementary atomic, ionic or molecular properties of processes.
