Recent Results from the St. George Recoil Mass Separator

Helium radiative capture plays a key role in many stellar environments beyond their hydrogen burning phase. Due to the low cross sections of these reactions at astrophysically relevant temperatures, direct measurements of these reactions pose significant challenges. The St. George recoil mass separator at the University of Notre Dame is designed to directly measure the products of helium radiative capture.

In this talk, recent results from several astrophysically relevant measurements conducted with St. George will be presented. This includes the study of ¹⁵N(α,α) elastic scattering and the capture reaction ²⁰Ne(α,γ)²⁴Mg. Future plans for (α,γ) reaction measurements will also be discussed.
