High Precision Measurement of Resonance States in $^{18}\textrm{Ne}$ , $^{30}\textrm{S}$, and $^{38}\textrm{Ca}$ Nuclei using the (p,t) Reaction, and Reaction Rates in the $\alpha$p- and rp-Processes

Abstract

Thermonuclear runaway reactions in type 1 X-ray burst are trigged by the breakout from the hot CNO cycles and is subsequently driven by $\alpha$p- and rp-processes. These time scales for the $\alpha$p- and rp-process are determined by the associated reaction rates, which depend exponentially on the associated resonance energies. High precision (p,t) measurement were preformed at iThemba LABS to examine resonance states in $^{18}\textrm{Ne}$, $^{30}\textrm{S}$, and $^{38}\textrm{Ca}$ nuclei using the K600 spectrometer with a dispersion matched beam. Preliminary analysis will be presented.
