Production of neutron-rich Ag, In and Sn isotopes from uranium carbide target of a high density has been investigated at the IRIS facility in the PLOG (PNPI-Legnaro-GANIL-Orsay) collaboration. The UC target material with a density of 12 g/cm3 was prepared by the method of powder metallurgy in a form of pellets of 2 mm thickness, 11 mm in diameter and grain dimensions of about 20 microns. The uranium target mass of 31g was exposed at a 1 GeV proton beam. For the ionization of produced species the electron beam - plasma ionization inside the target container (ionizing target) has been used. For the first time the new high density UC target material was exploited with the electron-plasma ionization. Yields of Ag and Sn isotopes have been measured in the target temperature range of (1900-2100) °C. The yields of some Pd, In and Cd isotopes were measured as well to compare to previously measured ones from a high density uranium carbide target having a ceramic-like structure. For the first time a nickel isotope was obtained from a high density UC target.
