To control the thickness of the F1486 1 23 target layer during the experiment, about 30 mu-g F1486 1 24 of 243Am were added to the target as a marker. F1486 1 25 Target thickness was 0.89 mg/cm2 at the energy of 231.1F1486 1 26 MeV, 0.76 mg/cm2 at 237.8 MeV and 0.65 mg/cm2 at 250.6 F1486 1 27 MeV. F1486 1 28 INC-SOURCE First beam intensity was 4 p mu-A, then it was F1486 1 29 reduced to 3 p mu-A. F1486 1 30 DETECTOR (MAGSP) The reaction products were analyzed by means F1486 1 31 of Dubna Gas Filled Recoil Separator (DGFRS-2). F1486 1 32 (SISD) The focal detector consisted of two 48x128-mm2 F1486 1 33 double-sided strip detectors with 48 1-mm horizontal F1486 1 34 strips on the front side and 128 1-mm-wide vertical F1486 1 35 strips on the back one. The first detector shielded a F1486 1 36 part of the rear detector. The back strips of 1-mm in F1486 1 37 width were paired together to form 110 strips of 2 mm F1486 1 38 in width. The focal detector was surrounded by eight F1486 1 39 60x120-mm2 side strip detectors, each with 8 strips, F1486 1 40 forming box with a depth of 120 mm. F1486 1 41 (MWPC) Two multiwire proportional chambers were used F1486 1 42 to register the nuclei passing through the separator. F1486 1 43 ERR-ANALYS The beam energy was measured with a systematic F1486 1 44 uncertainty of 1 MeV. F1486 1 45 (DATA-ERR) Total uncertainty is given. F1486 1 46 ADD-RES (DECAY) Decay properties of synthesized for the first F1486 1 47 time superheavy nuclides 268Sg, 272Hs,and 276Ds were F1486 1 48 investigated. F1486 1 49 MISC-COL (MISC) Excitation energy of the compound nucleus.
