1980Br26: 53Sc produced and identified in 238U(56Fe,X) at 8.3 MeV/nucleon at SuperHILAC facility in Berkeley; 19 6 events were assigned to 53Sc, but no half-life was measured
1997Li15: Si(53Sc,X),E=52-69 MeV/nucleon; measured reaction σ, deduced strong absorption radius; Glauber model
1998So03: 53Sc produced in 9Be(65Cu,X),E=64.5 MeV/nucleon reaction at GANIL. Measured half-life, Eγ, Iγ. Also 1995SoZX report from the same group
2010Cr02: 53Sc produced in fragmentation of E=130 MeV/nucleon 76Ge beam provided by the NSCL cyclotrons K500 and K1200 at NSCL. Isotopes separated with A1900 fragment separator. Time-of-flight technique. Measured β particles using NSCL Beta Counting System of three Si PIN detectors, a double-sided silicon strip detector and six single sided silicon strip detectors. Detected prompt and delayed γ rays in coin with fragments using 16 Ge detectors of the Segmented Germanium array. Measured half-life of 53Ca by fitting the decay curve of (53Sc)βγ correlated events. Also 2009Cr03 from the same group
