Two-prongs neutral charmed  D0 and \\v{D}0 -mesons decays were selected. Signal / background ratio was (51+/-17) / (38+/-13). Registration efficiency for mesons was defined and evaluation for charm production cross section at threshold energy is presented: sigma(c\\^c) = 7.1 +/- 2.4(stat.) +/- 1.4(syst.)
