Mass-7 destruction through $^7Be+d$ and $^7Li+d$ reactions, studied with ANASEN.

The astrophysically observed amount of $^7Li$ is only 25$\%$-33$\%$ of the one predicted by current models of Standard Big Bang Nucleosynthesis(SBBN). However, nuclear reactions between $^7Be+d$ are not well constrained experimentally and can destroy a good fraction of mass-7 nuclei under the conditions of SBBN. At the FSU accelerator laboratory, we performed a measurement of reactions between a beam of the radioactive isotope $^{7}$Be and the pure deuterium gas target located inside ANASEN (Array for Nuclear Astrophysics Studies with Exotic Nuclei). ANASEN is an active target detector system which tracks the charged particles between a position-sensitive proportional counter and 28 position-sensitive Silicon detectors, all backed up by CsI scintillation detectors. The experiment measures a continuous excitation function by slowing down the beam in the target gas, with a high detection efficiency for all relevant reaction channels, using single beam energy. We also performed an experiment for the mirror nuclear reaction $^7Li+d$ with ANASEN in active gas target mode. The preliminary results of these experiments along with details of ANASEN will be presented.
