198AT c Decay of (3+) ground state of {+202}Fr
198AT c 2014Ka23: {+202}Fr produced in {+149}Sm({+56}Fe,p2n) at
198AT2c E({+56}Fe)=244-275 MeV beam from GSI accelerator facility. Target=370
198AT3c |mg/cm{+2} thick enriched to 96.9% in {+149}Sm, and backed with
198AT4c 40 |mg/cm{+2} thick carbon backing and covered with a 10 |mg/cm{+2}
198AT5c layer of carbon. It was mounted on a rotating wheel. Evaporation
198AT6c residues were separated using SHIP facility at GSI, and implanted
198AT7c into the detection system consisting of 16-strip position sensitive
198AT8c Si detectors (PSSD), a pack of six Si strip detectors (BOX) at the
198AT9c back to detect escaping |a particles, and three time-of-flight
198ATAc detectors in front of PSSDs. Measured position and time correlations
198ATBc between evaporation residues (Er) and |a events, E|a, half-lives of
198ATCc ground states and isomers of {+202}Fr and {+198}At, Er-|a-|a
198ATDc correlations. Comparison with previous experimental results
198AT c (Er)|a|a correlated events were assigned to
