 60CO c  1957Ro54: From proton-induced spallation of copper at E(p)=400 MeV.
 60CO2c  Measured T{-1/2}. Chemical analysis, Geiger-Muller counter.
 60CO3c  Assignment of activity to {+60}Fe is uncertain.
 60CO c  2009Ru08: {+60}Fe isotope was chemically extracted in 2004 from a Cu
 60CO2c  beam dump, used at Paul Scherrer Institute, in which
 60CO3c  3.6|*10{+21} {I590}-MeV protons had been stopped between 1980 and 1992.
 60CO4c  Measured half-life of {+60}Fe from number of atoms of {+60}Fe and their
 60CO5c  activity in a sample containing over 10{+15} {+60}Fe atoms. Sample
 60CO6c  activity was measured by |g-ray spectroscopy in a
 60CO7c  low-background environment.
 60CO c  E|b=135 keV, E|g=27 and 59 keV reported by 1960Me09.

 60FE cP T$ from 2009Ru08, by measuring three quantities in the same sample:
 60FE2cP activity of {+60}Fe, the isotopic composition (ratio of number of
 60FE3cP {+60}Fe and Fe atoms), and the number of iron atoms in the sample.
