Study of astrophysical $\alpha + \quad^{\mathrm{22}}$Ne reaction using alpha transfer with TIARA and MDM spectrometer

In core He burning and C-shell burning of massive stars, the $^{\mathrm{22}}$Ne($\alpha $,n)$^{\mathrm{25}}$Mg reaction is considered to be a main neutron source driving the synthesis of nuclides in the A$=$60-90 mass range during the $s$ process. While a variety of attempts to experimentally determine the rate for this reaction at the Gamow window corresponding to $s$ process temperatures have been made either through direct $^{\mathrm{22}}$Ne($\alpha $,n)$^{\mathrm{25}}$Mg measurements or indirect measurements, uncertainties of some resonance parameters in $^{\mathrm{26}}$Mg has remained a longstanding problem. To address this problem, we performed an experiment using the $^{\mathrm{6}}$Li($^{\mathrm{22}}$Ne,$^{\mathrm{26}}$Mg)$d \quad \alpha $-transfer reaction at K150 cyclotron of Texas A{\&}M University. A $^{\mathrm{6}}$LiF target was bombarded with a 7 MeV/u $^{\mathrm{22}}$Ne beam. Deuterons, gamma-rays, and recoil Mg ions were detected in coincidence using a large Si detector array, TIARA, HPGe clover detectors, and an MDM spectrometer backed by an ionization chamber, respectively. Preliminary data from the experiment will be presented.
