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 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 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, ResoNeut and tested it with the stable beam reaction $^{12}$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 et al. Phys.Rev. 79, 032801 (2009)
