Аннотация: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 identifiedby a large gap in the rapidity distribution of final states.D∗± mesons were reconstructed from the decay D∗+→D0π+s with D0→K−π+ (+c.c.). Integrated and differential cross sections were compared to theoretical expectations
