Abstract / Description of output
Recently, the world's first radioactive Na-20 beams have been accelerated at the TRIUMF facility. Using the TRIUMF-UK Detector Array facility we have performed elastic scattering of this beam from protons in a CH2 target with the aim of determining resonance parameters of states in Mg-21. The region of excitation probed in Mg-21 has astrophysical importance because resonant contributions to the Na-20(p,gamma)Mg-21 reaction rate are thought to be part of the breakout path from the hot CNO cycle to the rp-process in x-ray bursters and perhaps novae. The data taken also serve a wider purpose in that comparisons may be made to isobaric analogue states in the mirror F-21 nucleus, and thus a study of Coulomb energy shifts may be undertaken.
An overview of the motivation, of the experiment, and a preliminary analysis of the data taken, is presented.
