      abstract     = {For bare lead ions, decelerated to the low beam energy of
                      10 MeV/u, the x-ray emission associated with radiative
                      recombination (RR) at 'cold collision' conditions has been
                      studied at the electron cooler of CRYRING@ESR at
                      GSI-Darmstadt. Utilizing dedicated x-ray detection chambers
                      installed at 0° and 180° observation geometry, we observed
                      for the very first time for stored ions the full x-ray
                      emission spectrum associated with RR under electron cooling
                      conditions. Most remarkably, no line distortion effects due
                      to delayed emission are present in the well resolved
                      spectra, spanning over a wide range of x-ray energies (from
                      about 5 to 100 keV) which enable to identify fine-structure
                      resolved Lyman, Balmer as well as Paschen x-ray lines along
                      with the RR transitions into the K-, L and M-shell of the
                      ions. To compare with theory, an elaborate theoretical model
                      has been applied. By considering the relativistic atomic
                      structure of Pb$^{81+}$, this model is based on a
                      sophisticated computation of the initial population
                      distribution via RR for all atomic levels up to Rydberg
                      states with principal quantum number $n=$ 165 in combination
                      with cascade calculations based on time-dependent rate
                      equations. Within the statistical accuracy, the experimental
                      x-ray line emission is in very good agreement with the
                      results of the theoretical model applied. Most notably, this
                      comparison sheds light on the contribution of prompt and
                      delayed X-ray emission (up to 70 ns) to the observed X-ray
                      spectra, originating in particular from Yrast transitions
                      into inner shells.},
