Description
The observation of γ-ray decays from the radioactive isotope $^{44}$Ti makes it one of the significant isotopes in the diagnosis of core-collapse supernovae (CCSNe) explosions. The abundance of 44Ti from CCSNe explosions has been shown to be strongly dependent on the $^{44}$Ti($\alpha,p$)$^{47}$V reaction rate, which destroys $^{44}$Ti. Direct measurements of the $^{44}$Ti($\alpha,p$) 47V reaction within the Gamow window (E$_{\mathrm{c.m.}}$ = 2 - 6 MeV) have been challenging due to the low cross sections and insufficient radioactive ion beam intensities. As a result, the reaction rate is still based on statistical models, which may not be reliable for α-induced reactions on N=Z nuclei due to the lower effective level density in the compound nucleus. To get the necessary experimental constraints of the $^{44}$Ti($\alpha,p$)$^{47}$V reaction such as the level density and branching ratios of the compound nucleus, $^{48}$Cr, a high-resolution 0$^{\circ}$ $^{50}$Cr($p,t$)$^{48}$Cr coincidence measurement was performed using the K600 magnetic spectrometer and an array of five double-sided silicon detectors called CAKE. Preliminary results from the coincidence measurements will be presented.
