论文摘要
通过两光子过渡（Rabbitt）的干扰重建Attsond殴打是一种技术，可用于确定光电离过程中原子过渡元素的阶段。在传统的Rabbitt方案中，所谓的“渐近近似”将测得的相视为与单光子电离过程相关的WIGNER相的总和，以及与连续体中与另外单个光子转变相关的持续元素 - 胞源（CC）相。在本文中，我们探讨了将渐近近似值扩展到多边界拉比特方案的可能性。然后，将来自该近似值的预测与基于求解时间依赖性的schrödinger方程来获得的{\ it i i i i}计算获得的结果进行了比较。
Reconstruction of Attosecond Beating By Interference of Two-photon Transitions (RABBITT) is a technique that can be used to determine the phases of atomic transition elements in photoionization processes. In the traditional RABBITT scheme, the so-called "asymptotic approximation" considers the measured phase as a sum of the Wigner phase linked to a single-photon ionization process and the continuum-continuum (cc) phase associated with further single-photon transitions in the continuum. In this paper, we explore the possibility of extending the asymptotic approximation to multi-sideband RABBITT schemes. The predictions from this approximation are then compared with results obtained by an {\it ab initio} calculation based on solving the time-dependent Schrödinger equation for atomic hydrogen.
