202AT H TYP=FUL$AUT=F.G. KONDEV$CIT=NDS 196, 342 (2024)$CUT=1-Sep-2023$
202AT c 1992Hu04: {+206}Fr was produced in {+nat}Ir({+20}Ne,xn) and
202AT2c {+181}Ta({+32}S,2p5n) reactions, and separated at the Leuven Isotope
202AT3c Separator On-Line (LISOL) facility. Recoils were implanted into a Mylar
202AT4c tape that periodically moved the source from the implantation station
202AT5c to the decay station. Detectors: 2 Ge and 1 Ge LEPS (|g rays), 1 Si(Li)
202AT6c (CE), several surface-barrier and PIPS detectors (|a particles).
202AT7c Measured: |a|g(t) and |a-X(t).
202AT c 2016Ly01: {+206}Fr was produced in the bombardment of 1.4 GeV protons
202AT2c on a Uranium carbide target at the ISOLDE-CERN facility. Recoils were
202AT3c selected by a high-resolution mass separator, injected into the ISCOOL
202AT4c cooler and buncher, resonantly excited with pulsed laser beams and
202AT5c implanted on a thin (20 |mg/cm{+2}) C foil. Alpha particles were
202AT6c measured using PIPS detectors
