The average thickness ofF150100100016 the Bi target segments on a given wheel varied from F150100100017 0.38 to 0.51 mg/cm2 + -0.02 mg/cm2. F150100100018 DETECTOR (SISD) GABRIELA detector array was used to detect the F150100100019 residues and their subsequent alpha decay or fission F150100100020 as well as gamma rays, X rays and conversion F150100100021 electrons. The evaporation residues pass through a F150100100022 Time of Flight detector composed of 2 emissive foils F150100100023 and 4 large-size (70x90 mm2) micro channel plate F150100100024 detectors. The residues are then implanted into a F150100100025 10x10 cm2 300 mu-m thick Double-sided Silicon Strip F150100100026 Detector. Particles escaping from the DSSD are F150100100027 detected in eight 6x5 cm2 DSSDs with 16 strips on each F150100100028 side. F150100100029 (GE)The Ge array consists of a large clover detector F150100100030 installed just behind the DSSD and 4 coaxial detectors F150100100031 forming a cross around the DSSD. F150100100032 METHOD (OLMS) The Separator for Heavy Elements Spectroscopy F150100100033 (SHELS) was used for separation of fusion-evaporation F150100100034 reaction products. F150100100035 (TOF,ASPEC) F150100100036 COMMENT *By author* The data were taken in two experiments. F150100100037 The first experiment was performed in two campaigns. F150100100038 During the first campaign, cyclotron beam energies of F150100100039 255 and 265 MeV were used, while in second the F150100100040 primary beam energies were 255 and 275 MeV. For the F150100100041 second experiment, primary beam energies of 255, 265 F150100100042 and 275 MeV were used. F150100100043 Cross sections were averaged over the first and second F150100100044 experiments. Mid-target energies are given.
