1995En07, 1997Be70: ⁷³Co identified in ⁹Be(²³⁸U,F) E=750 MeV/nucleon reaction; measured production cross section, residuals fission yields. Fully-stripped fission product separation, magnetic rigidity, trajectory, energy deposit, tof method

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 ⁷³Co and delayed-neutron emission probability. α total of 420 implants were detected, and four correlated βn coincidences were observed

2011Da08: ⁷³Co 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. Reaction products identified by mass, atomic number, charge, energy loss and time of flight. Measured half-life of ⁷³Co decay

2012Ra10 (also 2005Ma95): ⁷³Co produced by fragmentation of ⁸⁶Kr beam at 140 MeV/nucleon with a ⁹Be target at NSCL facility followed by fragment separation using A1900 fragment separator. Particle identification by energy loss and time-of-flight techniques. The ions were implanted in double-sided silicon strip (DSSD) detectors for fragment β detection. SeGA gamma-detector array containing 16 HPGe detectors was used for Eγ, Iγ, γγ, βγ coin, ion-β correlations and isotopic half-life measurements. Detailed shell-model calculations using NR78 residual interaction.

2014Xu07 (also 2014XuZZ thesis): ⁷³Co nuclide produced in ⁹Be(²³⁸U,F) reaction with ²³⁸U⁸⁶⁺ beam of 345 MeV/nucleon produced at the RIKEN accelerator complex. Identification of ⁷³Co 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. Isotopic yield measured based on α/Q spectrum and Z versus α/Q plot. Measured heavy fragments, 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. See also 2015BeZR conference report for production of ⁷³Co

Q-value: Estimated uncertainties (2017Wa10): 400 for Q(β^-), 570 for S(n) and Q(α), and 640 for S(p).

Q-value: S(2n)=9190 610, S(2p)=36430 640, Q(β^-n)=8740 400 (syst, 2017Wa10). Q(β^-2n)=1845 400 (syst, deduced by evaluators from Q(β^-) and S(2n) values in 2017Wa10).
