Abstract
We have performed a search for the beta+ decay of Mn-54 by looking for back-to-back 511-keV gamma rays in two high-purity Ge detectors. No e xcess of events above background was observed, and a limit of 5.7 x 10 (-7)% has been established for the beta+ branch. The significance of t his result for the use of Mn-54 as a cosmic ray chronometer is discuss ed.
