1997Be70: 58Sc identified in 9Be(238U,X) reaction at 750 MeV/nucleon. The fragments were mass separated using Fragment recoil separator and time-of-flight techniques. α total of 11 counts were assigned to 58Sc corresponding to cross section of 3 nb.
2005Ga01 (also 2003So21): 58Sc produced in fragmentation of 76Ge30+ beam on a 58Ni target at 61.8 MeV/nucleon. LISE3 achromatic spectrometer used to separate fragments; magnetic rigidity was tuned to optimize transmission of 62V and 64Cr fragments. Transmitted nuclei were identified by three consecutive Si detectors where two were used for energy loss and time-of-flight measurements while the third was used to determine their residual energies. Measured Eγ, Iγ, Iβ, γγ, βγ coin, γ(t), lifetimes with four Ge detectors placed around a thick Si telescope. Half-lives determined by fitting procedure involving five parameters: half-lives of mother, daughter and grand-daughter nuclei, the β-efficiency and the background rate over the 1 s collecting time.
