Query: Chaos {\sl vs} Thermalization in the Nuclear Shell Model   Generic signatures of quantum chaos found in realistic shell model
calculations are compared with thermal statistical equilibrium. We show the
similarity of the informational entropy of individual eigenfunctions in the
mean field basis to the thermodynamical entropy found from the level density.
Mean occupation numbers of single-particle orbitals agree with the Fermi-Dirac
distribution despite the strong nucleon interaction.
