Abstract / Description of output
Recently, the world's first radioactive 20Na 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 21Mg. The region of excitation probed in
21Mg has astrophysical importance because resonant
contributions to the 20Na(p,γ)21Mg 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 21F 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.
