The recent detection of a neutron star merger by the LIGO collaboration has renewed interest in laboratory studies of r -process elements. Accurate modeling and interpretation of the electromagnetic transients following the mergers requires computationally expensive calculations of both the structure and opacity of all trans-iron elements. To date, the necessary atomic data to benchmark structure codes are incomplete or, in some cases, absent entirely. Within the available laboratory studies, the literature on Au i and Au ii provides incomplete reports of the emission lines and level structures. We present a new study of Au i and Au ii lines and levels by exposing a solid gold target to plasma in the Compact Toroidal Hybrid (CTH) experiment at Auburn University. A wavelength range from 187 to 800 nm was studied. In Au i , 86 lines are observed, 43 of ...

淘金：Au i和Au ii的UV-VIS光谱新发射线

LIGO合作最近发现的中子星合并已经重新引起了对r过程元素的实验室研究的兴趣。合并后对电磁瞬变的准确建模和解释要求对所有反铁元素的结构和不透明度进行计算昂贵的计算。迄今为止，用于基准结构代码的必要原子数据不完整，或者在某些情况下完全不存在。在可用的实验室研究中，有关Au i和Au ii的文献提供了关于排放谱线和能级结构的不完整报告。通过在奥本大学的紧凑环形混合（CTH）实验中将固体金靶暴露于等离子体，我们提出了关于Au i和Au ii谱系和水平的新研究。研究了从187到800 nm的波长范围。在Au i中，观察到86行，
