 Abstract: 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
Schr\"odinger equation for atomic hydrogen.
