Description
Although the $^9\mathrm{Be}$ $|$ $^9\mathrm{B}$ isospin doublet has been studied along many years, the observation and prediction of the first 1/2+ state in $^9\mathrm{B}$ remains inconclusive. Different reactions have been used, where the experimental values oscillate between 0.80 to 1.90 MeV.
An experiment was proposed to measure the charge exchange reaction of $^9\mathrm{Be}$($^3\mathrm{He}$,$t$)$^9\mathrm{B}$ at the K600 spectrometer, iThemba LABS. This experiment combines the high-resolution spectrometer (K600) at 0$^\circ$ and a high efficiency detector array CAKE. Data analysis is performed by reconstruction of the low-lying excitation region in $^9\mathrm{B}$ through the momentum-analysis of the tritons, detected at the FOCAL PLANE in coincidence with the detection of the protons by CAKE.
Future work includes R-matrix analysis, required to unambiguously identify the first 1/2+ state in $^9\mathrm{B}$.
