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 phase associated with further single-photon transitions in the continuum. In this paper, we extend the asymptotic approximation to multi-sideband RABBITT schemes. The predictions from this approximation are then compared with results obtained by an ab initio calculation based on solving the time-dependent Schrödinger equation for atomic hydrogen.

多边带方案中过渡相位的分解，以通过双光子过渡的干扰来重建阿秒跳动

通过双光子跃迁的干扰来重建阿秒跳动（RABBITT）是一种可用于确定光电离过程中原子跃迁元素的相的技术。在传统的RABBITT方案中，所谓的渐近逼近法将测得的相位视为链接到单光子电离过程的Wigner相和与连续体中其他单光子跃迁相关的连续体-连续体相的总和。在本文中，我们将渐近逼近扩展到多边带RABBITT方案。然后，将该近似值的预测结果与基于求解与时间相关的原子氢Schrödinger方程的从头算计算所得的结果进行比较。
