Multichannel R-matrix analysis of elastic and inelastic resonances in the {sup 21}Na+ p compound system
- University of Edinburgh, Edinburgh, EH9 3JZ (United Kingdom)
A multichannel R-matrix formalism was used to fit {sup 21}Na+ p resonant elastic and inelastic scattering data taken at the TRIUMF UK detector array facility at TRIUMF-ISAC. Five resonances were observed corresponding to states in {sup 22}Mg above the proton threshold. Four of these corresponded to states seen in previous transfer reaction studies where firm spin-parity assignments could not be made. One new resonance, previously unobserved in any reaction, was also seen. Where possible, resonance energies, partial widths, and spin-parity values of these resonances were extracted. The correspondence between these states and possible analogs in the mirror nucleus {sup 22}Ne is discussed, as well as the relation to T=1 states in the nucleus {sup 22}Na.
