212AT c  2007Ku30:  {+216}Fr produced as daughter to {+220}Ac produced in a
212AT2c  {+209}Bi({+14}N,{Ip}2{In}){+220}Ac fusion evaporation reaction using
212AT3c  a 1.1 mg/cm{+2} thick target. The 5.6 MeV/u beam was provided by the
212AT4c  cyclotron of Heavy Ion Laboratory of Warsaw University at the
212AT5c  intensity of 30 pnA. Nuclei of interest were selected with the IGISOL
212AT6c  system, and those were implanted into a 30 |mg/cm{+2} thick carbon
212AT7c  foil. Silicon detector setup was used to measure E|a, |a(t), and |a|a
212AT8c  correlations.
