Experimental techniques to use the $(d,n)$ reaction for spectroscopy of low-lying proton-resonances

ORAL

Abstract

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. At the {\sc resolut} facility, we have used the $(d,n)$ reaction to populate the lowest $p$-- resonances in $^{26}$Si, and demonstrated the usefulness of this approach to populate the resonances of astrophysical interest[1]. In order to establisg 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. Performance data from this test-experiment and future plans for this setup will be presented. \\[4pt] [1] P.N. Peplowski {\it et al.} Phys.Rev.{\bf C 79}, 032801 (2009)
