Query: Recombination of low energy electrons with U$^{28+}$   We performed an extensive study of configuration mixing between the doubly
excited (doorway) states and complex multiply excited states of U$^{28+}$ near
its ionization threshold. The detailed investigation of complex spectrum and
analysis of the statistics of eigenstate components show that the dielectronic
(doorway) states weakly mixed with each other. However, they show substantial
mixing with the complex multiply excited states. This situation explains the
mechanism of low energy electron recombination with U$^{28+}$. We calculated
the energy averaged capture cross sections as a sum over dielectronic doorway
states and found our present calculation interprets well the experimental
recombination rates in the energy range of 1 to 100 eV.
