47SC c 1963Fu09: Measured |g|g(|q) lin pol using NaI detectors. Deduced
47SC2c mixing ratio of 489-keV transition.
47SC c 1966Fr14: {+47}Ca source from neutron irradiation of Ca(NO{-3}){-2}
47SC2c enriched to 20% in {+46}Ca. Measured E|g, I|g, |g(t) using Ge(Li)
47SC3c detector.
47SC c 1969Wo02: {+47}Ca source in the form of CaCl{-2}. Measured E|g, I|g
47SC2c using Ge(Li) detector, |g|g coincidences with NaI(Tl) crystal.
47SC c 1987Ju04: Measured E|b and |b|g-coincidences using |b spectrometer
47SC2c and NaI(Tl) detector.
47SC c 2022Ab01: {+47}Ca source obtained from isotope harvesting at the
47SC2c NSCL, MSU. Production was through {+48}Ca beam with E=140 MeV/nucleon
47SC3c incident on a flowing-water target, followed by chemical separation.
47SC4c Liquid scintillation counting to determine T{-1/2} of {+47}Ca and
47SC5c {+47}Sc. Measured E|g, I|g using HPGe detector.
