Query: General Time-Dependent Configuration-Interaction Singles II: The Atomic
  Case   We present a specialization of the grid-based implementation of the
time-dependent configuration-interaction singles described in the preceding
paper (arXiv:2204.09966) to the case of spherical symmetry. We describe the
intricate time propagator in detail, and conclude with a few example
calculations. Among these, of note are high-resolution photoelectron spectra in
the vicinity of the Fano resonances in photoionization of neon, and
spin-polarized photoelectrons from xenon, in agreement with recent experiments.
