56SC c 2004Li75: {+9}Be({+86}Kr{+34+},X) E=140 MeV/nucleon. Measured E|g,
56SC2c I|g using a double-sided Si microstrip detector (DSSD) and the MSU
56SC3c segmented Germanium Array (SeGA). Identity of particle from energy
56SC4c loss and time of flight from a PIN detector, the NSCL |b calorimeter,
56SC5c and scintillator. The SeGA array was arranged around the |b counting
56SC6c system and comprised six Ge detectors, A1900 fragment separator.
56SC c 2010Cr02: E=130 MeV/nucleon; measured E|g, I|g, |g|g, and half-lives
56SC2c using 16 detectors from the Segmented Germanium Array (SeGA) and BCS
56SC3c detectors at the National Superconducting Cyclotron Laboratory (NSCL).
56SC4c E=130 MeV/nucleon {+76}Ge{+30+} beam provided by the K500 and K1200
56SC5c cyclotrons at NSCL at Michigan State University. Isotopes separated
56SC6c with A1900 fragment separator. Time-of-flight technique. Fully stripped
56SC7c secondary fragments were sent to NSCL Beta Counting System (BCS).
56SC8c System of three Si PIN detectors, a double-sided silicon strip detector
56SC9c and six single sided silicon strip detectors. Detected |g rays using
56SCAc 16 Ge detectors of the Segmented Germanium array. Measured half-life of
56SCBc {+56m}Sc by fitting the (implant correlated) isomeric transition decay
56SCCc curve to a single exponential function with a constant background
56SC c 2010Cr02 and 2004Li75 are from NSCL-MSU, with some of the same authors.
56SC c 2012Ka36: {+238}U beam at E=345 MeV/nucleon provided by the RIBF
56SC2c accelerator complex at RIKEN facility. Fission fragments were separated
56SC3c and analyzed by BigRIPS separator, transported to focal plane of
56SC4c ZeroDegree spectrometer and finally implanted in an aluminum stopper.
56SC5c Particle identification was achieved by |DE-tof-B|r method.
56SC6c Delayed gamma rays from microsecond isomers were detected by three
56SC7c clover-type HPGe detectors. Measured E|g, I|g, |g|g-coin, isomer
56SC8c half-life. Comparison with previous studies.
56SC c 2020Mi13: E=345 MeV/nucleon {+70}Zn beam produced from the Beam
56SC2c Factory (RIBF) at RIKEN. Target was 2.2 g/cm{+2} {+9}Be. Fragments
56SC3c were separated and identified by the time-of-flight magnetic-rigidity
56SC4c (TOF-B|r-|DE) method and energy-loss using the BigRIPS separator, the
56SC5c SHARAQ spectrometer, CVD diamond and silicon strip detectors.
56SC6c Measured mass-to-charge ratios, E|g, I|g using a plastic stopper, two
56SC7c HPGe clover detectors and a plastic veto detector.
56SC9c Comparisons with theoretical calculations.
56SC cG $Assignment of observed transitions to feed the 26-ms g.s. was
56SC2cG determined in 2010Cr02 from a half-life curve of |b-decay events
56SC3cG correlated with the {+56}Sc implants as well as with one of the five
56SC4cG prompt |g rays from the decay of the 290-ns isomer. Deduced half-life
56SC5cG was 30 ms {I5} in agreement with the half-life of lower-spin {+56}Sc
56SC6cG state.
