Description

Charge-exchange reactions at intermediary energies is a powerful tool to study spin-isospin excitations in nuclei. In particular, these type of reactions serve as a direct method for the extraction of the Gamow-Teller (GT) transition strengths which are of importance for a variety of applications where weak transition strengths play a role (e.g. electron capture and $\beta$-decay in stellar evolution, neutrino nucleosynthesis, etc.). GT transitions in the $\beta^+$ direction have been studied extensively through $(t,{}^{3}\text{He})$ charge-exchange reactions. The $(d,{}^{2}\text{He})$ reaction is another and potentially even more powerful probe for measurements of $B(\text{GT}^+)$ strengths, since the detection of ${}^{2}$He (two protons in the relative singlet ${}^{1}S_0$ state) ensures automatically that the reaction goes through spin-flip components. However, the major disadvantage lies in the detection and kinematic reconstruction of the ${}^{2}$He particle. The AT-TPC, a detector based on time projection chamber, provides a unique technique for achieving these type of experiments. Feasibility studies of $(d,{}^{2}\text{He})$ reactions using this technique have been done with GEANT4 simulations. In this contribution, the current status of the project will be presented.
