Description

The 9Be - 9B isospin doublet carries fundamental significance for both nuclear structure and nuclear astrophysics studies. The first excited ½+ state in 9Be is already well established. However, its isobaric analogue state in 9B has not been unambiguously determined yet. Theoretically, the 9B nucleus can either be described using a cluster model with two unbound α particles held together by a covalent proton or using the shell model as a 8Be core + proton in the s-d shell. Both theoretical predictions based on different models as well as experimental investigations yield largely discrepant results for the excitation energy of this state. This presentation describes preliminary results from an experiment performed at iThemba LABS that aimed to characterize the first ½+ state in 9B with the 9Be(3He,t) reaction at the K600 spectrometer.
