The average thickness ofF1501 1 16 the Bi target segments on a given wheel varied from F1501 1 17 0.38 to 0.51 mg/cm2 + -0.02 mg/cm2. F1501 1 18 DETECTOR (SISD) GABRIELA detector array was used to detect the F1501 1 19 residues and their subsequent alpha decay or fission F1501 1 20 as well as gamma rays, X rays and conversion F1501 1 21 electrons. The evaporation residues pass through a F1501 1 22 Time of Flight detector composed of 2 emissive foils F1501 1 23 and 4 large-size (70x90 mm2) micro channel plate F1501 1 24 detectors. The residues are then implanted into a F1501 1 25 10x10 cm2 300 mu-m thick Double-sided Silicon Strip F1501 1 26 Detector. Particles escaping from the DSSD are F1501 1 27 detected in eight 6x5 cm2 DSSDs with 16 strips on each F1501 1 28 side. F1501 1 29 (GE)The Ge array consists of a large clover detector F1501 1 30 installed just behind the DSSD and 4 coaxial detectors F1501 1 31 forming a cross around the DSSD. F1501 1 32 METHOD (OLMS) The Separator for Heavy Elements Spectroscopy F1501 1 33 (SHELS) was used for separation of fusion-evaporation F1501 1 34 reaction products. F1501 1 35 (TOF,ASPEC) F1501 1 36 COMMENT *By author* The data were taken in two experiments. F1501 1 37 The first experiment was performed in two campaigns. F1501 1 38 During the first campaign, cyclotron beam energies of F1501 1 39 255 and 265 MeV were used, while in second the F1501 1 40 primary beam energies were 255 and 275 MeV. For the F1501 1 41 second experiment, primary beam energies of 255, 265 F1501 1 42 and 275 MeV were used. F1501 1 43 Cross sections were averaged over the first and second F1501 1 44 experiments. Mid-target energies are given. F1501 1 45 HISTORY (20240408C) F1501 1 46 ENDBIB 44 0 F1501 1 47 COMMON 1 3 F1501 1 48 EN-ERR F1501 1 49 MEV F1501 1 50 3.
