Abstract
DESY-HERA. Measurement of the diffractive scattering cross sections in the process gamma* p --& gt; X N, where N is either a proton or a nucleonic system of mass & lt; 4GeV in c.m. energy range 60 to 245 GeV and mass of the system X up to 15 GeV. Data come from deep inelastic events taken during the 1993 HERA run with a 26.7 GeV electron beam and 820 GeV proton beam with a total luminosity of 543 nb-1.
