  Recent results of the study of the particle-phonon coupling (PC) effects in
odd magic and semi-magic nuclei within the self-consistent theory of finite
Fermi systems are reviewed. In addition to the usual pole diagrams, the
non-pole ones are considered. Their contributions are often of a crucial
importance. PC corrections to the single-particle energies for $^{40}$Ca and
$^{208}$Pb are presented. The quadrupole moments of odd In and Sb isotopes, the
odd-proton neighbors of even Sn isotopes, are presented also with accounting
for the PC corrections. At last, recently announced problem of extremely high
values charge radii of heavy Ca isotopes is solved in terms of a consistent
consideration of the PC effects. In all the cases, rather good description of
the data is obtained.
