Low energy charged particle reactions determine the nuclear burning in different phases of stellar evolution. The ashes provide the seed and fuel for subsequent evolution phases and also determine the seed material for nuclear processes in subsequent cataclysmic events. The charged particle reactions have extremely small cross sections. The direct measurement is extremely challenging because...

\noindent The \(^{30}P(p,\gamma)^{31}S\) proton capture reaction is a bottleneck for nucleosynthesis towards heavier nuclei during nova outbursts. This reaction is inaccessible experimentally in the relevant energy region, but its reaction rate can be probed using the \(^{30}P(d,n)^{31}S\) transfer reaction. By determining the energies and spin assignments of low lying states in \(^{31}S\)...

The reaction rate of 12C(α,γ)16O is critical in modeling the evolution of stars throughout the many stages of their lifecycles. The nucleosynthesis that occurs there plays a key role in the development of life in the universe. Together with the 3α process, these rates determine the ratio of 12C/16O. Yet despite its importance, a precise determination of the cross section has remained elusive....
