CHIANTI原子数据库包含原子能级、波长、辐射跃迁概率和碰撞激发数据，用于大量天体物理学感兴趣的离子。CHIANTI还包括一套IDL例程来计算合成光谱并进行等离子诊断。版本5已经发布，其中包括几个新特性，以及许多离子的新数据。CHIANTI的新特点是：将电离和重组率纳入单个激发能级，作为填充原子能级的手段；从Fe II到Fe XXIV的Kα和Kβ发射数据；Fe XVII至Fe XXIII高能结构的新数据；以及对x射线范围内的能级能量和线识别、多温度粒子分布和任何用户定义的辐射场的光激发的完整重新评估。数据库中已经存在的离子的新数据，以及数据库早期版本中不存在的离子的数据也包括在内。版本5的CHIANTI代表了在x射线范围内的线发射率和合成光谱计算的重大改进，并扩展和改进了所有其他波长范围的理论光谱计算。
The CHIANTI atomic database contains atomic energy levels, wavelengths, radiative transition probabilities, and collisional excitation data for a large number of ions of astrophysical interest. CHIANTI also includes a suite of IDL routines to calculate synthetic spectra and carry out plasma diagnostics. Version 5 has been released, which includes several new features, as well as new data for many ions. The new features in CHIANTI are as follows: the inclusion of ionization and recombination rates to individual excited levels as a means to populate atomic levels; data for Kα and Kβ emission from Fe II to Fe XXIV; new data for high-energy configurations in Fe XVII to Fe XXIII; and a complete reassessment of level energies and line identifications in the X-ray range, multitemperature particle distributions, and photoexcitation from any user-defined radiation field. New data for ions already in the database, as well as data for ions not present in earlier versions of the database, are also included. Version 5 of CHIANTI represents a major improvement in the calculation of line emissivities and synthetic spectra in the X-ray range and expands and improves theoretical spectra calculations in all other wavelength ranges.
