The Ammosov–Delone–Krainov (ADK) and Perelomov–Popov–Terent’ev (PPT) ionization models were widely used in strong-field physics and attosecond science due to their many attractive advantages such as simpler analytical formula, less computational demands, and satisfied accuracy of ionization rate. Based on the density-functional theory, we systematically determine accurate structure parameters of 25 atoms, 24 positive ions and 13 negative ions and tabulate for future applications. The wave function with correct asymptotic behavior is obtained by solving the time-independent Schrödinger equation with B-spline basis sets and the accurate structure parameters are extracted from this wave function in the asymptotic region. The accuracies of structure parameters are carefully examined by comparing the ionization probabilities (or yields) calculated by PPT and ADK models with those of solving the three-dimensional time-dependent Schrödinger equation and the experimental data.

原子强场电离模型中结构参数的确定

Ammosov-Delone-Krainov（ADK）和Perelomov-Popov-Terent'ev（PPT）电离模型由于具有许多诱人的优势，例如解析公式更简单，计算需求更少以及满足电离速率的精度。基于密度泛函理论，我们系统地确定了25个原子，24个正离子和13个负离子的准确结构参数，并列出了将来的应用。通过用B样条基集求解与时间无关的Schrödinger方程，可以得到具有正确渐近行为的波动函数，并从该波动函数的渐近区域中提取准确的结构参数。
