放射性同位素的核均方电荷半径是通过激光光谱学的同位素位移测量得到的。为了提取增量(r(2))的值，需要估计原子场和质量移位因子。本文总结了目前用于计算复杂开壳原子的原子场和质量位移因子的实验和理论方法，包括单电荷Y(Z=39)的5s(2)S-1(0)-4d5pP-1(1)和4d5sD-3(2)-4d5pP-3(1)跃迁。
Nuclear mean-square charge radii of radioactive isotopes are obtained from isotope-shift measurements using laser spectroscopy. To extract the values of delta(r(2)) the atomic field and mass shift factors need to be evaluated. We here summarize the currently available experimental and theoretical techniques for calculating the atomic field and mass shift factors for complex, open-shell atoms, including the 5s(2) S-1(0) - 4d5p P-1(1) and 4d5s D-3(2) - 4d5p P-3(1) transitions for singly charged yttrium (Z = 39).
