论文摘要
在本文中，我们介绍了在Ganil-Spiral2设施的Gisele Laser Laser实验室获得的第一个高分辨率激光光谱结果，以准备使用S $^3 $ -LOW ENERGY分支进行的首次实验。对ERBIUM和TIN的中子缺陷放射性同位素的研究代表了最早以S $^3 $进行研究的物理病例。为这些元素的稳定同位素提供了测得的同位素变度和超细结构数据。使用$ 4F^{12} 6S^2 $ $^3H_6 \ rightArrow 4f^{12}（^3 H）6S6P $ $ j = 5 $ j = 5 $ atomic transition（415 nm）和TIN isOtopes研究了$ 5S^25p^3p_2（^25p^3p_0） （^3p_1）$原子过渡（286.4 nm），用作激光设置的基准。 Additionally, the tin isotopes were studied by the $5s^25p6s (^3P_1) \rightarrow 5s^25p6p (^3P_2)$ atomic transition (811.6 nm), for which new isotope-shift data was obtained and the corresponding field-shift $F_{812}$ and mass-shift $M_{812}$ factors are presented.
In this paper we present the first high-resolution laser spectroscopy results obtained at the GISELE laser laboratory of the GANIL-SPIRAL2 facility, in preparation for the first experiments with the S$^3$-Low Energy Branch. Studies of neutron-deficient radioactive isotopes of erbium and tin represent the first physics cases to be studied at S$^3$. The measured isotope-shift and hyperfine structure data are presented for stable isotopes of these elements. The erbium isotopes were studied using the $4f^{12}6s^2$ $^3H_6 \rightarrow 4f^{12}(^3 H)6s6p$ $J = 5$ atomic transition (415 nm) and the tin isotopes were studied by the $5s^25p^2 (^3P_0) \rightarrow 5s^25p6s (^3P_1)$ atomic transition (286.4 nm), and are used as a benchmark of the laser setup. Additionally, the tin isotopes were studied by the $5s^25p6s (^3P_1) \rightarrow 5s^25p6p (^3P_2)$ atomic transition (811.6 nm), for which new isotope-shift data was obtained and the corresponding field-shift $F_{812}$ and mass-shift $M_{812}$ factors are presented.
