Description
We present preliminary results of a recent experiment performed to measure the $^{10}$Be(t,p)$^{12}$Be reaction with the SOLARIS solenoidal spectrometer. This is among the first experiments using a long-lived radioisotopes in conjunction with the re-accelerated beam facility (ReA6) at the Facility for Rare Isotope Beams. SOLARIS provides excellent resolution (about 150~keV FWHM) and background rejection capabilities for direct-reaction measurements. Using a re-accelerated $^{10}$Be beam at 9.6~MeV/u on a titanium tritide target we observed bound states of $^{12}$Be and those above the one- and two-neutron separation energies.The data reaffirm assignments and observations of a previous study in normal kinematics, while also offering new insights that hint at a resolution of some outstanding questions with regards to the structure of $^{12}$Be. In this talk, we will discuss the experiment, the analysis procedure and the preliminary results.
