4. 28Al Half-life Measurement at the NSL

28Al Half-life Measurement at the NSL

Published: October 2025 Brodeur

Lead Author(s): B. Liu

The half-life of ²⁸Al was measured for the first time using a radioactive ion beam at the TwinSol facility of the Nuclear Science Laboratory of the University of Notre Dame. The new result, t_1/2=134.432(34) s, is consistent with most of the previously reported ²⁸Al half-life values except for one highly discrepant measurement and may warrant another independent measurement.
