2014Ro14: ⁷¹Kr produced in the fragmentation of 70 MeV/nucleon ⁷⁸Kr beam with nickel target. Fragments selected with the LISE3 separator at GANIL and identified by time-of-flight and energy loss. Measured half-life of ⁷¹Kr ground-state decay by (fragment)β, (fragment)γ correlations using four Si detectors (an energy loss ΔE detector, a degrade, DSSD and Si(Li)) for particles surrounded by four HPGe Clover detectors, three EXOGAM, and one mini-clover Ge detector for γ rays.

2018Wi08: intense production (see Fig. 1 in the paper) of beam of ⁷¹Kr nuclei in ⁹Be(⁷⁸Kr,X),E-345 MeV/nucleon at RIBF-RIKEN

2019Si33: ⁷¹Kr produced at the RIBF-RIKEN facility in the ⁹Be(¹²⁴Xe,X) reaction at E=345 MeV/nucleon. Fragments were separated in the first stage of BigRIPS and then identified by measuring ΔE, tof and Bρ using BigRIPS and the ZeroDegree spectrometer, followed by implantation of products into the beta-counting system WAS3ABi, consisting of a double-sided silicon-strip detector. Measured time distribution of (implanted ions)β⁺-correlated events, and deduced half-life of ⁷¹Kr decay

2022Wa34: ⁷¹Kr produced in ⁹Be(⁹²Mo,X),E=140 MeV/nucleon reaction, followed by separation of ions of interest using A1900 fragment separator and a Radio Frequency Fragment Separator (RFFS) at the Coupled Cyclotron Facility of NSCL-MSU. The ions in the cocktail beam were implanted into the β-counting station (BCS), which consisted of a stack of PIN detector (PIN2) and Double-Sided Silicon-Strip Detector (DSSSD) for detection of implants, surrounded by the SeGA array of 16 HPGe detectors for γ detection. Measured Eγ, Iγ, (implants)β-coin, (implants)(β-delayed protons)-coin, (implants)γγ-coin, (implants)βγ-coin, T_1/2 of decay of ⁷¹Kr. Deduced absolute (per 100 decays of parent) number of βγ-coin events, β events, absolute (per 100 decays of parent) intensities of γ rays, and intensities of β-delayed protons.

1964Fl03: ^70-72Br or ^70-72Kr claimed to have been produced in Ni(²⁰Ne,X) E=140 MeV reaction and a delayed proton group of 2.5 MeV with a half-life of 23 s 4. It is not possible to associate this observation with a presently known activity
