1994Cz02: 65Fe produced from fragmentation of 500-MeV/u 86Kr beam. Measured ion-β- time correlation, deduced half-life.
1992BeZP: 65Fe produced from fragmentation of 500-MeV/u 86Kr particles incident on a Be target followed by particle separation using a fragment recoil separator; these were then implanted in a Si detector for β- detection.
1990Tu01: 65Fe from 800-MeV proton produced fragmentation and fission on a natural Th target and mass separation by a time-of-flight isochronous spectrometer with dZ/Z=1.6% (FWHM) and dQ/Q=1.4% (FWHM). Measured isotopic masses.
