Abstract
Radioactive ^(54)Mn, suggested as a clock for measuring the lifetime of heavy cosmic rays, has a poorly known B-decay halflife estimated to be in the range from ~10^(5) to 10^(7) yr. Some years ago Koch et al. concluded from measurements of the Mn/Fe ratio that a significant fraction of low-energy (
