类O等电子序列的R矩阵电子碰撞激发数据
R-matrix electron-impact excitation data for the O-like iso-electronic sequence
摘要：
天体物理等离子体代码是建立在原子数据库上的。在现有的原子数据库中，类氧离子的R矩阵电子碰撞激发数据有限。用类O离子进行等离子体诊断的准确性取决于原子数据的可用性和准确性。这对于未来配备下一代高分辨率光谱仪的天文台来说尤其重要。为了获得从\ion{Ne}{III}到\ion{Zn}{XXIII}的类O离子的能级分辨的有效碰撞强度（即，Ne $^{2+}$至Zn $^{22+}$）。这包括每个离子最高到$nl=5d$的跃迁。我们还旨在评估新数据的准确性，以及它们对太阳大气等离子体诊断的影响，与CHIANTI数据库中的数据相比。对类O等电子序列进行了大规模R矩阵中间耦合框架变换计算。对于每个离子，630个精细结构水平被包括在配置相互作用目标和紧密耦合碰撞扩展。目前的结果（能级，振子强度，和有效的碰撞强度）选定的离子在整个等电子序列进行比较与档案数据库和文献。对于跨等电子序列的选定离子。我们发现一般协议与以前的几个R-矩阵计算的碰撞强度。我们说明了一些太阳等离子体诊断现有的CHIANTI原子模型的基础上扭曲波数据的改进。电子碰撞激发数据根据原子数据和分析结构（ADAS）数据类adf 04存档，并将在OPEN-ADAS中提供。
英文摘要：
Astrophysical plasma codes are built on atomic databases. In the current atomic databases, R-matrix electron-impact excitation data of O-like ions are limited. The accuracy of plasma diagnostics with O-like ions depends on the availability and accuracy of the atomic data. This is particularly relevant in the context of future observatories equipped with the next generation of high-resolution spectrometers. To obtain level-resolved effective collision strengths of O-like ions from \ion{Ne}{III} to \ion{Zn}{XXIII} (i.e., Ne$^{2+}$ to Zn$^{22+}$) over a wide range of temperatures. This includes transitions up to $nl=5d$ for each ion. We also aim to assess the accuracy of the new data, as well as their impact on solar atmosphere plasma diagnostics, compared to those available within the CHIANTI database. A large-scale R-matrix intermediate coupling frame transformation calculations were performed systematically for the O-like iso-electronic sequence. For each ion, 630 fine-structure levels were included in both the configuration interaction target and close-coupling collision expansions. The present results (energy levels, oscillator strengths, and effective collision strengths) of selected ions across the iso-electronic sequence are compared with those in archival databases and the literature. For selected ions across the iso-electronic sequence. We find general agreement with the few previous R-matrix calculations of collision strengths. We illustrate the improvements for a few solar plasma diagnostics over existing CHIANTI atomic models based on distorted wave data. The electron-impact excitation data are archived according to the Atomic Data and Analysis Structure (ADAS) data class adf04 and will be available in OPEN-ADAS.
