63FE c 2009Ma22: {+nat}U(p,X) {+63}Mn source was produced by bombardment of a
63FE2c natural uranium target with 1.4 GeV proton beam from the ISOLDE
63FE3c facility at CERN. Fragments were separated with the High Resolution
63FE4c Seperator (HRS) and selected ions were transported to the decay
63FE5c station. |b particles were detected with a thin fast-response plastic
63FE6c scintillator (start) and |g rays were detected with two fast-response
63FE7c |g scintillators (stop) and two Ge detectors. Measured E|g, I|g, E|b,
63FE8c |g|g-coin, |b|g(t), |b|g|g(t). Deduced levels, T{-1/2}.
63FE c 2005GaZR: {+58}Ni({+76}Ge,X) {+63}Mn source was produced by
63FE2c fragmentation of 61.8 MeV/nucleon {+76}Ge beam on a 150-|mm-thick
63FE3c {+58}Ni target at GANIL. Fragments were separated by the LISE3 mass
63FE4c spectrometer and identified using a telescope of three Si detectors. |g
63FE5c rays were detected with 4 Clover Ge detectors. Measured E|g, I|g,
63FE6c |g|g-coin. Deduced levels, J, |p, |b-decay branching ratios, log {Ift}.
63FE7c Comparisons with QPRA calculations.
63FE c 2002MaZN: Ta({+86}Kr,X) {+63}Mn source was produced by fragmentation
63FE2c of 57.8 MeV/nucleon {+86}Kr beam on a 49.8 mg/cm{+2} tantalum target
63FE3c at GANIL. Fragments were separated by the LISE2000 separator and
63FE4c implanted in a telescope of SI(Li) detectors. |g rays were detected
63FE5c with four EXOGAM Ge detectors. Measured E|g, I|g, |g(t). Deduced
63FE6c parent T{-1/2}
63FE c 1985Bo49: W({+76}Se,X) {+63}Mn source was produced by fragmentation of
63FE2c 11.4 MeV/nucleon {+76}Ge beam on a 36 mg/cm{+2} natural W target at
63FE3c GSI. Fragments were separated by the GSI on-line mass separator and
63FE4c transported to the counting positions. |b particles were detected with
63FE5c a 4|p |b detector and a |b-ray telescope consisting of a Si |DE and a
63FE6c lucite E detectors; |g rays were detected with two |g-ray detectors.
63FE7c Measured E|g, E|b, |b|g-coin, |b(t). Deduced parent T{-1/2}.
63FE c Others:
63FE c 1999So20,1999Le67: {+58}Ni({+86}Kr,X) {+63}Mn source was produced by
63FE2c fragmentation of E=60.4 MeV/nucleon {+86}Kr beam on a {+58}Ni target at
63FE3c GANIL. The detector setup is similar to that in 2005GaZR. Measured
63FE4c |g(t). Deduced parent T{-1/2}.
63FE c 1999Ha05: U(p,X) E=1 GeV proton beam from the ISOLDE facility at CERN.
63FE2c Measured |b-delayed n(t) using a 4|p {+3}He neutron counter. Deduced
63FE3c parent T{-1/2}
63FE c 1997AmZZ,1995AmZX: Be({+86}Kr,X) E=500 MeV/nucleon at GSI. Fragments
63FE2c were separated with the FRS separator. Measured implant-|b(t).
63FE3c Deduced parent T{-1/2}
63FE c The decay scheme is that from 2009Ma22 and is incomplete due to
63FE2c a large gap between Q=8749 {I6} and the reported highest level at
63FE3c E=1543.
63FE cB IB$From I|g intensity balance at each level, unless otherwise noted.
63FE2cB Quoted values should be considered as approximate due to incomplete
63FE3cB decay scheme.
63FE cB IB(A)$Deduced by 2005GaZR. The authors only state that %I|b(357)=31 is
63FE2cB from I|g(357|g) and %I|b(1132)=32 is from I|g(1132|g), but they could
63FE3cB have been deduced by the authors from I|g intensity balance at the two
63FE4cB levels and the total |b intensity. Note that the net I|g feedings at
63FE5cB 357 and 1132 levels using I|g from 2005GaZR are 80 and 66,
63FE6cB respectively, and its ratio 80/66 is inconsistent with
63FE7cB %I|b(357)/%I|b(1132)=31/32. It is very likely that additional feeding
63FE8cB to 357 level could have been used by the authors in deducing %I|b but
63FE9cB is missing in their decay scheme, e.g., the 93.8|g from 451 level to
63FEacB 357 level in the decay scheme of 2009Ma22, which doesn't report any
63FEbcB %I|b. Based on I|g data in 2009Ma22, the ratio of the two net I|g
63FEccB feedings is 63/65 and is in a good agreement with
63FEdcB %I|b(357)/%I|b(1132)=31/32 in 2005GaZR, indicating %I|b(357) and
63FEecB %I|b(1132) from 2005GaZR are good for use.
63FE cG E,RI$From 2009Ma22, unless otherwise noted. |DE|g is not given
63FE2cG by the authors and the evaluator has assumed |DE|g=0.5 keV in the
63FE3cG fitting procedure to obtain E(level) values
63FE cL E$From a least-squares fit to |g-ray energies, assuming |DE|g=0.5 keV
63FE cL J$From Adopted Levels
63FE cL T$From |b|g(t) in 2009Ma22 for excited states, adopted in Adopted
63FE2cL Levels
63MN P 0.0 5/2(-) 0.276 S 6 8749 6
63MN cP J,T$From Adopted Levels of {+63}Mn. Adopted T{-1/2} is weighted average
63MN2cP of 0.275 s {I4} (1999Ha05), 0.322 s {I23} (1999Le67,1999So20), 0.24 s
63MN3cP {I3} (1997AmZZ), 0.29 s {I2} (1995AmZX), and 0.25 s {I4} (1985Bo49).
63FE N 0.49 1
63FE cN NR$From %I|b(357)=31 and %I|b(1132)=32 in 2005GaZR, which is likely
63FE2cN deduced from measured I|g intensity balance at the two levels and
63FE3cN total I|b intensity, independent from the rest of the decay scheme.
63FE4cN But it should be considered as approximate due to incomplete decay
63FE5cN scheme.

63FE cB IB$from 2005GaZR. The authors only state it is deduced from measured
