Query: Accelerated Recombination due to Resonant Deexcitation of Metastable
  States   In a recombining plasma the metastable states are known to accumulate
population thereby slowing down the recombination process. We show that an
account of the doubly-excited autoionizing states, formed due to collisional
recombination of metastable ions, results in a significant acceleration of
recombination. A fully time-dependent collisional-radiative (CR) modeling for
stripped ions of carbon recombining in a cold dense plasma demonstrates an
order of magnitude faster recombination of He-like ions. The CR model used in
calculations is discussed in detail.
