1992We04: ⁷¹Co produced and identified by fragmentation of 500 MeV/nucleon ⁸⁶Kr beam incident on a beryllium target followed by mass separation in a magnetic spectrometer using in addition time-of-flight and energy loss measurements for nuclide identification. Measured production cross section.

1998Am04 (also 1997AmZZ thesis): ⁷¹Co produced in the fragmentation of ⁸⁶Kr beam at 500 MeV/nucleon with ⁹Be target at GSI facility. Fragment recoil separator used to separate fragments. Magnetic rigidity and time-of-flight method used to identify the isotope. Measured half-life

2005GaZR thesis (also 2003So21): ⁷¹Co produced in the fragmentation of ⁷⁶Ge beam at 61.8 MeV/nucleon with ⁵⁸Ni target at GANIL facility. Lise3 spectrometer was used to separate fragments. Magnetic rigidity and time-of-flight method used to identify the isotope. Measured β, half-life

2011Da08 (also 2004Sa59, 2002MaZN thesis): ⁷¹Co produced in the fragmentation of 57.8 MeV/nucleon ⁸⁶Kr beam impinged on 50 mg/cm² thick tantalum target, followed by separation of fragments 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. Products identified by mass, atomic number, charge, energy loss and time of flight. Measured γ rays, βγ-coin, half-life of ⁷¹Co decay

2012Ra10 (also 2005Ma95): ⁷¹Co produced in fragmentation of ⁸⁶Kr beam at 140 MeV/nucleon with a ⁹Be target at NSCL-MSU facility, followed by separation of fragments using A1900 fragment separator. Particle identification was carried out by energy loss (E-ΔE) and time-of-flight techniques. The ions were implanted in double-sided silicon strip (DSSD) detectors for fragment and β detection. SeGA gamma-detector array containing 16 HPGe detectors was used for βγ-coin, ion-β correlations and isotopic half-life measurements.

2019Ly02: ⁷¹Co from primary beam of ⁸⁶Kr at 140 MeV/nucleon impinged on a ⁹Be target at the NSCL-MSU facility. ⁷¹Co separated using A1900 separator, and identified using energy loss and time-of-flight information from a plastic scintillator detector and two silicon PIN detectors, followed by implantation of ⁷¹Co nuclei in a 1 mm thick double-sided silicon strip detector (DSSD) which was placed in the geometric center of the Summing NaI(Tl) (SuN) detector. Measured half-life of ⁷¹Co decay, and total absorption γ spectrum (TAGS) from ⁷¹Co decay

2020MoZS: one of the evaluators (B. Singh) enquired from the first author (α. Morales) about the possibility of extracting %β^-n for the decay of ⁷²Co investigated by 2016Mo07. Dr. α. Morales in her e-mail communication of May 26, 2020 sent us extracted decay branches for %β^-n and %β^-2n for ^{70,71,72,73,74}Co from analysis of intensities of γ rays emitted in the decay chains of several isotopes, including granddaughters and great-granddaughters. However, some concern was expressed by α. Morales about the quality of the deduced %β^-n and %β^-2n branching ratios, thus the value of %β^-n is listed by the evaluators here as approximate.
