C173500100012 SAMPLE (82-PB-208,ENR=0.984) C173500100013 (82-PB-207,ENR=0.011) C173500100014 (82-PB-206,ENR=0.005) Targets consisted of metallic C173500100015 208Pb deposited on 35 +- 5-microg/cm2 natC backings to C173500100016 a thickness of 470 +- 60 microg/cm2. The Pb layer was C173500100017 covered with 5 +- 2-microg/cm2 natC to prevent the C173500100018 loss of target material caused by the beam. C173500100019 PART-DET (A) C173500100020 DETECTOR (SISD,MWPC) All detectors consist of 300-microm-thick C173500100021 Si mounted on 0.15-microm-thick Al. A multiwire C173500100022 proportional counter (MWPC) was mounted upstream of C173500100023 the focal plane and used to distinguish implantation C173500100024 events from radioactive decays. The Berkeley Gas C173500100025 Separator fill gas was He at 0.5 torr. C173500100026 METHOD (ASPEC) Cross sections were deduced from the count of C173500100027 alpha-decay chains. A total of 33 decays chains C173500100028 originating from 262Bh and 2 decay chains originating C173500100029 from 261Bh were observed. C173500100030 ERR-ANALYS (ERR-S) Uncertainties in measured values in this C173500100031 paper are reported at the 1 sigma [68%] confidence C173500100032 level. C173500100033 (EN-ERR) The absolute uncertainty in the projectile C173500100034 energies from the Cyclotron is ~1% C173500100035 HISTORY (20170403C) BP C173500100036 ENDBIB 34 0 C173500100037 COMMON 1 3 C173500100038 EN-ERR C173500100039 PER-CENT C173500100040 1.
