Description

In this work, I will present the preliminary results of the study of the resonance states in 26 S by
elastic scattering of 22 Mg(α,α) 22 Mg. Resonances in 26 S are important to determine the reaction rate of the 22 Mg(α,p) 25 Al [1] and 25 Al(p,γ) 26 Si. The study of the resonances was performed using the active target ATTPC [2] with a re-accelerated radioactive beam produced in the ReA3 installation at NSCL (USA).A beam of 22 Mg at around 4.9 MeV/u impinged in the 4 He gaz volume in ATTPC. Information on the Bρ, and angle was used to deduce the excitation energy function in 26 Si.
