Accelerator mass spectrometry measurements and model calculations of iron‐60 production rates in meteorites

Abstract— The cosmogenic radionuclide 60Fe (T1/2 = 1.49 Ma) was measured in two iron meteorites as well as in the magnetic fractions of a stony‐iron and a stony meteorite by means of accelerator mass spectrometry (AMS).
