Oscillator Strengths and Electron Collisional Strengths of Atoms and Ions Relevant to Stellar Observations

Dr. Tayal将对S、Fe、Ni和Cu原子和离子的振子强度、光电离和电子碰撞激发截面进行精确而全面的计算。这些原子数据是对恒星光谱进行定量分析所必需的，特别是在紫外线下观察到的光谱。这些研究还将为原子结构和碰撞过程的基本方面提供进一步的物理见解。＊＊＊

95-28945 Tayal, Swaraj Dr. Tayal will carry out accurate and comprehensive calculations of oscillator strengths, photoionization and electron collisional excitation cross sections of S, Fe, Ni and Cu atoms and ions. These atomic data are required for a quantitative analysis of stellar spectra, especially those observed in the ultraviolet. These studies also will provide further physical insight into the basic aspects of atomic structure and collisional processes. ***
