Angular distributions of high spin states produced via ²⁷Al(α,d)²⁹Si

The investigation of nuclear structure in the mass 16-60 region has provided rich experimental data to test microscopic theory. Previously our group has used the tools and techniques of multi-gamma spectroscopy to chart out the high-spin yrast states in this mass region. It has been shown¹ that (α,d) reactions also have a preference for high spin states since the proton and neutron from the deuteron can both occupy the same state of maximal J. I will present work using the FSU Super Engie Split Pole Spectrograph (SE-SPS). Angular distributions for states produced via ²⁷Al(α,d)²⁹Si will be shown for high spin states for the first time. Comparison of these states will be made with the FSU shell model² interaction.
