  $D^{*+/-}$ production in the diffractive interactions was measured with the
ZEUS detector at HERA using integrated luminosities of 44 pb$^{-1}$ in deep
inelastic scattering and 38 pb$^{-1}$ in photoproduction processes.
  Diffractive interactions were identified by a large gap in the rapidity
distribution of final states. $D^{*+/-}$ mesons were reconstructed from the
decay $D^{*+} -> D^0\pi_s^+$ with {$D^0 -> K^-\pi^+$} (+c.c.). Integrated and
differential cross sections were compared to theoretical expectations.
