Update on the 60Fe half-life

In a recent paper by Kutschera et al. a weighted mean value for the half-life of 60 Fe has been given with ( 2 . 60 ± 0 . 05 ) Ma. Since this value cannot be understood from the available literature, one has to consider modifications in the Paul-Scherrer-Institute/Technical University of Munich (PSI-TUM) value. For this measurement the PSI group has later on published a number of decaying nuclei with a larger error. Here we give an updated value for the measured 60 Fe activity. This leads to a PSI-TUM value of ( 2 . 61 ± 0 . 05 ) Ma, which in turn results in a weighted average including available values from the literature which is identical to the weighted average of Kutschera et al., cited above.
