220TH c  {+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.
220TH7c  Measured E|a, I|a, E|g, I|g, |a|g-coin, (Er)|a-coin and T{-1/2} of
220TH8c  {+224}U g.s.
220TH c  Cross section with lower limit of 600 nb {I100} was obtained.

224U 3cP Others: T{-1/2}({+224}U)=0.7 ms +0.5-0.2, measured by 1991An13;
224U 4cP 1.0 ms {i4}, measured by 1992To02.
220TH c  %|a({+224}U)=100 in 1997Ar05, from a calculated upper limit for |e
220TH2c  decay branch of <1.2|*10{+-4}% (1973Ta30).
220TH3c  The partial half-life of {+224}U |b{++} decay has been
220TH2c  calculated as >100 s in 1997Mo25.
220TH D  NO CALCULATION FOR T1/2(EC) OF 224U IS GIVEN IN 1997MoZW.

220TH cL E$from E|g. E|a=8095 {I11} feeding this level gives level energy
220TH2cL of 391 {I14}. The energies of the 2+ to 0+ and 4+ to 2+ transitions
220TH3cL in {+220}Th were previously assigned as 373.3 keV {I1} keV and
220TH4cL and 386.5 keV {I1} (2006Re15), respectively.
220TH5cL Based on the observation of (8095|a)(386.5|g)-coin, and on the energy
220TH6cL of 8095|a group relative to that of 8479|a, 2014Lo10 suggest that
220TH7cL previous assignment is incorrect, and that the ordering of the 373.3-
220TH8cL and 386.5-keV transitions should be reversed, thus defining 386.5 keV
220TH9cL as the first excited 2+ state in {+220}Th
