SPECTR-W3

The information accumulated in the SPECTR-W3 ADB contains over 450,000 records and includes factual experimental and theoretical data on ionization potentials, energy levels, wavelengths, radiation transition probabilities, oscillator strengths, and (optionally) the parameters of analytical approximations of electron-collisional cross-sections and rates for atoms and ions. Those data were extracted from publications in physical journals, proceedings of the related conferences, special-purpose publications on atomic data, and provided directly by authors. The information is supplied with references to the original sources and comments, elucidating the details of experimental measurements or calculations, where necessary and available. To date, the SPECTR-W3 ADB is the largest factual database in the world containing the information on spectral properties of multicharged ions.

SPECTR-W3 ADB中累积的信息包含超过450,000条记录，涵盖了关于电离势、能级、波长、辐射跃迁概率、振子强度等实验与理论数据，并可选地包括电子碰撞截面及速率的解析近似参数。这些数据源自物理期刊的出版物、相关会议的论文集、专门针对原子数据的出版物，以及作者直接提供的内容。信息提供时附带原始来源的引用及注释，用以阐释实验测量或计算的细节，如有必要且信息可用。截至目前，SPECTR-W3 ADB是全球最大的关于多电荷离子光谱性质的事实数据库。
