 38AR c  2008Le12: {+38}K isomer was produced in the reaction Ta(p,X) with a 500
 38AR2c  MeV beam provided by the ISAC facility at TRIUMF on a 22 g/cm{+2}
 38AR3c  Ta target. |b particles were measured by the Scintillating Electron
 38AR4c  Positron Tagging Array (SCEPTAR) of 20 plastic scintillators and |g
 38AR5c  rays were detected by a 8|p array of 20 HPGe detectors. Measured E|g,
 38AR6c  I|g, E|b, I|b, |g|b-coin, |g|b(t). Deduced supperallowed |b{++}
 38AR7c  decay branching ratio and Ft, parent T{-1/2}.
 38AR c  2010Ba43: {+38m}K was produced at the ISAC facility at TRIUMF in
 38AR2c  spallation reaction by bombarding CaZrO{-3} target with a 500 MeV
 38AR3c  proton beam. |b particles were detected with a 4|p continuous gas-flow
 38AR4c  proportional |b counter. Sample purity was monitored by an HPGe
 38AR5c  |g-ray detector. Measured parent T{-1/2}.
 38AR c  2000Bb01: {+38m}K produced by {+38}Ar(p,n) with 7 MeV proton beam
 38AR2c  provided by the University of Auckland tandem. Measured positron
 38AR3c  spectrum, parent T{-1/2}
 38AR c  1983Ko22: {+38m}K produced via {+12}C({+28}Si,pn) with 120 MeV {+28}Si
 38AR2c  beam provided by the Chalk River on-line isotope separator. Measured
 38AR3c  parent T{-1/2}.
 38AR c  2005Go11, 2003Tr01, 2000Go54: measured E|b, (recoil)|b, deduced
 38AR2c  |b(|n) correlations
 38AR c  2005Sa44: mass analysis
 38AR c  1998Di15: measured |b spectrum, (recoil)|b coin
 38AR c  1998Ha36: measured positron yield
 38AR c  1997Be35: measured optical isotope shifts, mean square radii
 38AR c  1994Ha43: measured |b-delayed |g spectra, deduced limits
 38AR c  1984Ch22, 1981Ch34: measured Fermi |b decay T{-1/2}
 38AR c  1978Th02: measured |b spectrum, T{-1/2}
 38AR c  1976Wi08, 1975Sq01, 1972Ha82: measured T{-1/2}

 38AR c  Total decay energy deposit of 6042.69 {I23} keV calculated using
 38AR2c  RADLIST code is in agreement with the expected value 6042.3 {I3}
 38AR3c  indicating the completeness of the decay scheme.

 38K 4dP (2000Bb01), 924.46 ms {I14} (2010Ba43), using the Normalised Residual
 38K 5dP Method (NRM) with a reduced |h{+2}=2.9, and weighted average gives
 38K 6dP 924.35 {I25} with a reduced |h{+2}=4.4. The evaluator has adopted
 38K 7dP 924.4 ms {I3} by considering results from both methods. Others (in ms):
 38K 8dP 948 {I10} (1961Ja22); 938 {I8} (1960Ja12); 944 {I12} (1960Li05); 970

 38K  dP T$2000Bb01 recommended 924.24 ms {I27} from an average of their value
 38K 2dP and that of 1983Ko22, others were omitted on the premise that
 38K 3dP error analysis might not have been adequate.
