Description

Reliable $(\alpha ,n)$, $(\alpha ,p)$, and $(p,\alpha )$ cross sections and reaction rates are critical to modeling nucleosynthesis in novae, X-ray bursts, and neutrino-driven winds, yet direct measurements at astrophysically relevant energies remain limited. \par
The Multi-Sampling Ionization Chamber (MUSIC) active-target detector is designed for precise measurements of ionization energy loss in nuclear reactions. In this talk the working principle of MUSIC will be discussed , its role in studying $\alpha$-induced reactions, and recent experimental highlights including recent MUSIC campaigns at Argonne’s ATLAS and FRIB such as the first excitation function for the reaction (^{59}\mathrm{Cu}(p,\alpha)^{56}\mathrm{Ni}) importatnt to understand the Ni-Cu cycle and the key hot-CNO reaction (^{14}\mathrm{O}(\alpha,p)^{17}\mathrm{F}).
