Study of resonances in $^{23}\mathrm{Mg}(p, \gamma)^{24}\mathrm{Al}$ via neutron transfer to analog states in $^{24}$Na
ORAL
Abstract
According to sensitivity studies, the $^{23}$Mg$(p,\gamma)^{24}$Al reaction has a significant influence on the production of the radionuclides $^{22}$Na and $^{26g}$Al in oxygen-neon novae. At nova temperatures, this reaction is thought to be dominated by a single resonance at $E_r \sim 480$ keV, whose strength has previously been measured using a radioactive $^{23}$Mg beam and recoil mass spectrometer. To further constrain the rate of this reaction, we have undertaken a spectroscopic study of the mirror states of $^{23}$Mg$(p,\gamma)^{24}$Al resonances, using the single-neutron transfer reaction $^{23}$Na$(d,p)^{24}$Na in inverse kinematics. The experiment utilized the TIARA silicon detector array coupled to four germanium clovers and the MDM magnetic spectrometer at the Texas A&M University Cyclotron Institute, serving as the commissioning experiment for the ``TIARA for Texas'' (T40) campaign at Texas A&M. In this talk, I will give an overview of the experimental setup; present preliminary results from the commissioning experiment; and discuss future plans for the T40 collaboration.
