220TH c  2014Lo10: {+224}U produced using the fusion evaporation reaction
220TH2c  {+206}Pb({+22}Ne,4n), with 119 MeV {+22}Ne beam produced at FLNR
220TH3c  facility (Dubna). Evaporation residue (Er) was separated using SHELS
220TH4c  separator and then passed through a tof system and implanted into a
220TH5c  DSSD in front of a HPGe. Position and time-correlated |a decays were
220TH6c  used to identify Er. Measured E|a, I|a, E|g, I|g, |a|g-coin,
220TH7c  (Er)|a-coin and T{-1/2} of {+224}U g.s. Cross section with lower limit
220TH8c  of 600 nb {I100} was obtained.
220TH c  2019Pa45: {+220}Th activity produced as |a decay daughter of {+224}U.
220TH2c  The {+224}U activity was produced in the {+20}Ne+{+208}Pb experiment
220TH3c  with E=109 MeV at the Acceleratory Laboratory at the University of
220TH4c  Jyvaskyla. Recoils separated in the RITU gas-filled separator and
220TH5c  implanted into focal plane. Measured E|a, |a(t), using a suite of two
220TH6c  DSSDs and 28 pin diode detectors.

220TH cL E$from Adopted Levels. E|a=8095 {I11} feeding this level gives level
220TH2cL energy of 386 {I13}. The energies of the 2+ to 0+ and 4+ to 2+
220TH3cL transitions in {+220}Th were previously assigned as 373.3 keV {I1} and
220TH4cL 386.5 keV {I1} (2006Re15), respectively. Based on the observation of
220TH5cL (8095|a)(386.5|g)-coin, and on the energy of 8095|a group relative to
220TH6cL that of 8479|a, 2014Lo10 suggest that previous assignment is incorrect,
220TH7cL and that the ordering of the 373.3- and 386.5-keV transitions should be
220TH8cL reversed, thus defining 386.5 keV as the first excited 2+ state in
220TH9cL {+220}Th
