抄録

Astrophysical ¹⁸Ne(α,p)²¹Na reaction is one of the most probable breakout routes, which lead to the rp-process from the hot-CNO cycle, converting the initial CNO elements into heavier elements in Type I x-ray bursters. Presently, there is no much experimental cross-section data reported at the energy of astrophysical interest, and resonant spectroscopic information in compound ²²Mg is scarce as well. The experiment has been carried out by using the CNS radioactive ion beam separator (CRIB). Resonant properties in ²²Mg have been studied via the resonant elastic scattering of ²¹Na+p, and cross section of the time-reversal reaction of ²¹Na(p,α)¹⁸Ne been measured simultaneously. A wide excitation energy region up to E_x ∼ 9.5 MeV in ²²Mg has been scanned with a thick-target method. Some preliminary results will be reported.
