AB - The Al-23(p, gamma)Si-24 stellar reaction rate has a significant impact on the light-curve emitted in X-ray bursts. Theoretical calculations show that the reaction rate is mainly determined by the properties of direct capture as well as low-lying 2(+) states and a possible 4(+) state in Si-24. Currently, there is little experimental information on the properties of these states.

In this proceeding we will present a new experimental study to investigate this reaction, using the surrogate reaction Al-23(d,n) at 47 AMeV at the National Superconducting Cyclotron Laboratory (NSCL). We will discuss our new experimental setup which allows us to use full kinematics employing the Gamma-Ray Energy Tracking In-beam Nuclear Array (GRETINA) to detect the gamma-rays following the de-excitation of excited states of the reaction products and the Low Energy Neutron Detector Array (LENDA) to detect the recoiling neutrons. The S800 was used for identification of the Si-24 recoils. As a proof of principle to show the feasibility of this concept the Q-value spectrum of Mg-22(d,n)Al-23 is reconstructed.
