Description
The K600 magnetic spectrometer and the CAKE silicon detector array form a powerful tool for coincidence measurements in many nuclear physics measurements including nuclear astrophysics. These instruments have been used, among others, in studies measuring proton decays from $\alpha$-unbound states in $^{22}$Mg through the $^{24}$Mg$(p,t)$$^{22}$Mg reaction to study the $^{18}$Ne$(\alpha,p)$$^{21}$Na cross section relevant in type-I X-ray bursts (XRBs). The thermonuclear reaction rate of $^{18}$Ne$(\alpha,p)$$^{21}$Na is one of the important rates that affect the behaviour of the XRB lightcurve. This talk will examine the $^{22}$Mg$(p,t)$$^{22}$Mg experiment that was performed at iThemba LABS, Cape Town and discuss future experiments with the $^{28}$Si$(p,t)$$^{26}$Si reaction to study proton decays from $\alpha$-unbound states in $^{26}$Si to study the cross section and thermonuclear reaction rate of $^{22}$Mg$(\alpha,p)$$^{25}$Al and its influence on type-I XRBs.
