Abstract

The level structure of ²⁵Al has been studied at the ORNL Holifield Radioactive Ion Beam Facility (HRIBF) by measuring the angular and energy distributions of alpha particles from the ²⁸Si(p,α) ²⁵Al reaction. Proton beams (∼10 nA) at laboratory energies of 40- and 42-MeV were generated by the 25 MV tandem accelerator and bombarded a natural silicon target (50 μg/cm²). Alpha particles were detected and identified in the Silicon Detector Array (SIDAR) in the " telescope" configuration [1]. Eighteen levels have been observed and spins for several have been constrained through a distorted-wave Born approximation (DWBA) analysis of the angular distributions. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial- ShareAlikeLicence.
