38K c 2008Le12: {+38m}K was produced by Ta(p,X) reaction at E=500 MeV beam
38K 2c provided by ISAC facility at TRIUMF. Reaction products were ionized
38K 3c followed by mass separation to finally produce a 30 keV beam of {+38}K
38K 4c and {+38m}K ions. The ions were implanted on to a tape for decay
38K 5c measurements. |b particles were detected with an array of 20 plastic
38K 6c scintillation detectors and |g rays were detected with an 8|p array of
38K 7c 20 HPGe detectors. Measured E|g, I|g, |b|g-coin. Deduced isomer
38K 8c half-life, decay branching ratio.
38K c 2010Ba43: {+38m}K was produced at the ISAC facility at TRIUMF in
38K 2c spallation reaction by bombarding CaZrO{-3} target with E=500 MeV
38K 3c proton beam provided by the cyclotron at TRIUMF. Reaction products were
38K 4c ionized with a surface ionization source. |b particles were detected
38K 5c with a 4|p continuous gas-flow proportional counter. Sample purity was
38K 6c monitored by an HPGe |g-ray detector. Measured E|g, decay-time
38K 7c distribution. Deduced isomer half-life. Comparison with earlier
38K 8c measurements
