F148300100026 SAMPLE The targets consisted of the enriched isotopes and wereF148300100027 produced by electrodeposition on a 0.62-mg/cm2 Ti F148300100028 backing. Targets consisted of 12 sectors which were F148300100029 mounted on a periphery of a disk with a diameter of F148300100030 24 cm and 10-mm target layer opened for the beam and F148300100031 were rotated at 980 rpm. The total active surface F148300100032 area was 69 mg/cm2. F148300100033 DETECTOR (MAGSP) The reaction products were analyzed by means F148300100034 of Dubna Gas Filled Recoil Separator (DGFRS-2). F148300100035 (SISD) The focal detector of 48 mm in vertical and F148300100036 220 mm in horizontal directions consisted of two 48 x F148300100037 128-mm double-sided silicon strip detectors (DSSDs). F148300100038 They were mounted one by one in such a way that the F148300100039 front detector shielded part of the rear detector. F148300100040 Forty eight 1-mm front horizontal strips of both F148300100041 detectors were connected. The back strips were paired F148300100042 together to form 110 strips of 2 mm width. These F148300100043 detectors were surrounded by eight silicon single- F148300100044 sided 60 x 120-mm side detectors (SSSDs), each with F148300100045 eight strips, forming a box with a depth of 120 mm. F148300100046 (MWPC) Two multiwire proportional chambers were used F148300100047 to register the nuclei passing through the separator. F148300100048 ADD-RES (DECAY) The decay properties of 286Fl and 287Fl, as F148300100049 well as their descendants, have been refined from 25 F148300100050 and 69 new decay chains, respectively. F148300100051 ERR-ANALYS The beam energy was measured with a systematic F148300100052 uncertainty of 1 MeV. F148300100053 (DATA-ERR) Total uncertainty is given.
