Spectroscopic study on \textsuperscript{39}Ca for classical nova endpoint nucleosynthesis

 In classical nova nucleosythesis repeated proton capture reactions and beta-decays produce proton-rich isotopes and the endpoint of this nucleosynthesis typically occurs in nuclei close to A $\sim$ 40. There is currently a discrepancy between the observed and predicted isotopic abundances in this mass region. One particular reaction, $^{38}$K(p,$\gamma$)$^{39}$Ca is important in this regard. Nova simulations show that this reaction can affect isotopic abundances of $^{38}$Ar, $^{39}$Ar, and $^{40}$Ca significantly when the reaction rate is varied by its maximum uncertainty. Thus, it is important to constrain uncertainties of this reaction rate to accurately predict isotopic abundances.\\

Although a recent direct measurement has reduced the reaction rate uncertainty, further work is needed to constrain this reaction rate. Specifically, additional measurements to precisely probe the low energy resonances within the Gamow window. To that end, I will present the results of measuring these astrophysically important levels in $^{39}$Ca using the reaction $^{40}$Ca(d,t)$^{39}$Ca. The experiment was carried out at the Maier-Leibnitz-Laboratory (MLL) using the 14 MV MP-Tandem accelerator and Quadrupole 3-Dipole (Q3D) magnetic spectrograph.
