Spectroscopy of Low-Lying Proton-Resonances using the $(d,n)$ Reaction in Inverse Kinematics*

Studies of rp-process nucleosynthesis in stellar explosions show that establishing the lowest $l=0$ and $l=1$ resonances is the most important step to determine reaction rates in the astrophysical $rp$--process path. In order to establish the $(d,n)$ reaction as a standard technique for the spectroscopy of astrophysical resonances, we have developed a compact setup of low-energy Neutron-detectors, {\sc resoneut} and tested it with the stable beam reaction $\mathrm{^{12}C(d,n)^{13}N}$ in inverse kinematics. At the {\sc resolut} in-flight radioactive beam facility, we have used the new detector system to investigate the $l=0$ and $l=1$ resonance spectrum in $^{18}$Ne and $^{26}$Si. Results from these experiments and the implications on proton-induced nucleosynthesis rates will be discussed.
