Improvements to the Study of <sup>20</sup>Ne(α,γ)<sup>24</sup>Mg at Astrophysical Energies Using St. George

ORAL

Abstract

Recoils from the 20Ne(α,γ)24 reaction have been successfully measured in inverse kinematics on the St. George recoil mass separator system at astrophysically relevant energies.

However, the first of these measurements suffered from significant background, setting an upper limit on the strength of resonances that could be studied.

Recently, a Wien Filter was added to the beam line in order to enhance the purity of the beam being sent to the HIPPO helium gas-jet target.

I will discuss the improvements to the 20Ne(α,γ)24 reaction study as a result of this addition.
