The lifetimes of the excited states of 55 Mn between 1.5 and 2.7 MeV were measured using nuclear resonance ?uorescence. The absolute lifetimes of the excited levels were determined from simultaneous measurements of manganese and aluminum. In this approach, the precisely known aluminum states serves as a means to normalize the results. Our ?ndings differ from the evaluated level lifetimes in ENSDF, but agree with earlier nuclear resonance ?uorescence measurements.
