1997Be70, 1995En07: ⁷⁴Co identified in ⁹Be(²³⁸U,F), E=750 MeV/nucleon reaction; fully-stripped fission products separated using Fragment-Recoil Separator (FRS). Measured magnetic rigidity, trajectory, energy deposit, time-of-flight, production cross section and residuals fission yields.

2005Ma59 (also 2005Ma95): ⁷⁴Co produced by fragmentation of ⁸⁶Kr beam at 140 MeV/nucleon in a ⁹Be target, followed by analysis of reaction products using A1900 spectrometer. Measured γ, β, γ(implanted ion) coin

2010Ho12: ⁹Be(⁸⁶Kr,X) E=140 MeV/nucleon; fully-ionized ⁸⁶Kr beam, A1900 fragment separator at NSCL facility using Bρ-ΔE-Bρ method. After separation, the mixed beam was implanted into the NSCL β-counting system (BCS) consisting of stacks of Si PIN detectors, a double-sided Si strip detector (DSSD) for implantation of ions, and six single-sided Si strip detectors (SSSD) followed by two Si PIN diodes. The identification of each implanted event was made from energy loss, time-of-flight information and magnetic rigidity. The implantation detector measured time and position of ion implantations and β decays. Neutrons were detected with NERO detector. Measured β- and βn-correlated events with ion implants; half-life of ⁷⁴Co and delayed-neutron emission probability from a total of 331 implants, and 16 correlated βn coincidences

2011Da08: ⁷⁴Co produced in the fragmentation of 57.8 MeV/nucleon ⁸⁶Kr beam impinged on 50 mg/cm² thick tantalum target using LISE-2000 spectrometer at GANIL facility. Detector system included a three-element Si-detector telescope containing a double-sided silicon-strip detector (DSSSD) backed by a Si(Li) detector and surrounded by four clover type EXOGAM Ge detectors. Product identified by mass, atomic number, charge, energy loss and time of flight. Measured half-life of ⁷⁴Co decay. See also 2002MaZN thesis reporting some of the same results

2014Xu07: ⁷⁴Co nuclide produced in ⁹Be(²³⁸U,F) reaction with a ²³⁸U⁸⁶⁺ beam of 345 MeV/nucleon produced by the RIKEN accelerator complex. Identification of ⁷⁴Co nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments (ΔE-Bρ-tof method) using BigRIPS fragment separator and ZeroDegree Spectrometer (ZDS) at RIBF-RIKEN facility. Based on α/Q spectrum and Z versus α/Q plot. Measured heavy fragment, β and γ spectra using wide-range active silicon strip stopper array (WAS3ABi) for β and ion detection, and EUROBALL-RIKEN Cluster array for γ detection. Decay curves were obtained from time differences between implantation and correlated β decays. Also 2014XuZZ thesis by the first author of 2014Xu07.
