Experiments with synchrotron radiation will be undertaken to understand how ionization and rearrangement mechanisms evolve as a function of energy. Resonant scattering theory and relativistic multiconfiguraton self-consistent field calculations will be used to interpret the results. In a second phase of the project the mechanisms will be studied whereby an atom in a very strong laser field absorbs a large number of photons through above-threshold ionization. A model for this process, quantizing the radiation field and making the interaction relativistic, will be developed in terms of time dependent formal scattering theory and its predictions compared with experiment.

将进行同步辐射实验，以了解电离和重排机制是如何作为能量的函数演变的。共振散射理论和相对论多组态自洽场计算将被用来解释结果。在该项目的第二阶段，将研究在非常强的激光场中的原子通过高于阈值的电离吸收大量光子的机制。根据含时形式散射理论及其与实验的比较，我们将建立一个量子化辐射场并使相互作用成为相对论的模型。
