Stacked target thicknesses were 0.585, 0.856,C256700100011 1.215 and 0.721mg/cm2. C256700100012 The Al foil thicknesses were 5.033 and 0.98mg/cm2. C256700100013 (82-PB-208,ENR=0.9900) C256700100014 (82-PB-207,ENR=0.0070) C256700100015 (82-PB-206,ENR=0.0030) C256700100016 DETECTOR (SI) Each Pb target-degrader assembly was at the C256700100017 center of a cubical vacuum chamber, where four C256700100018 300-mm2 Canberra PIPS silicon detectors viewed the C256700100019 target-degrader assembly. C256700100020 INC-SOURCE (KINDT) Proton beams with energy of 500 MeV and C256700100021 intensity of approx. 70 mu-A struck Ta metal C256700100022 production targets. Beams of radioactive 11Li were C256700100023 extracted with energies up to 18.4 keV, C256700100024 mass-separated by passage through two dipole magnets, C256700100025 and accelerated to their final energy by C256700100026 radio-frequency quadrupole and drift tube linear C256700100027 accelerators. The "center-of-target" 11Li beam energiesC256700100028 were 26.1, 27.4, 28.5 and 32.7MeV in the four cubes C256700100029 METHOD (ACTIV) The 11Li beam was pulsed on for less than 5 C256700100030 ns and shut off for 172 ns, during which time the C256700100031 alpha decay of any stopped evaporation residue was C256700100032 measured. Product nuclei were identified by alpha C256700100033 particle energy. C256700100034 ERR-ANALYS (DATA-ERR) No information on source of uncertainties C256700100035 HISTORY (20191120C) Compiled by S.H.

C256700200006 HIVAP and similar calculations predict very small C256700200007 cross section for complete fusion product 216At. For C256700200008 negligibly small production cross section 216At was C256700200009 removed from the 212Atm/215At ambiguity.
