Abstract

A series of astrophysical measurements was recently completed at TRIUMF, related to the unknown total rate of the 21Na(p, γ)22Mg reaction. With a high intensity 21Na beam from the ISAC facility, the DRAGON recoil mass spectrometer was used to directly measure seven resonances at center of mass energies from to 1135 keV and determine their respective contributions to the 21Na(p, γ)22Mg reaction rate in novae and x-ray bursts, as well as their impact on 22Na production in novae. This study also allowed the investigation of different excited states in 22Mg; proposed decays and spin assignments are given for the 6246, 6329, and 6609 keV levels. [Copyright &y& Elsevier]

12. Multichannel R-matrix analysis of elastic and inelastic resonances in the 20,21Na+p compound systems

Author

Ruiz, C., Aliotta, M., Azuma, R.E., Boyd, R.N., Buchmann, L., Chen, A., Clarke, N.M., D'Auria, J.M., Davinson, T., Fulton, B.R., Groombridge, D., Hutcheon, D., Laird, A.M., Murphy, A.S., Pearson, J., Roberts, I., Robinson, A., Sarazin, F., Shotter, A.C., and Walden, P.

Abstract

Resonant scattering studies were performed using radioactive 20,21Na beams at ISAC between energies of 0.5 keV/u and 1.5 keV/u. Intensities of up to 1 × 108 /sec were used with thick CH2 targets, and elastic and inelastic proton resonances were observed corresponding to states in 21,22Mg by detecting recoil protons using the LEDA silicon array. A multichannel R-Matrix formalism was used to fit the excitation functions leading to the deduction of partial widths and spin-parity assignments. In certain cases definite spin-parity assignments could be made without fitting angular distributions due to the constraining nature of Coulomb-interfering resonances. Where possible, analogue assignments are made in the A=22, T=1, system based on the 21Na+p analysis. [Copyright &y& Elsevier]

Abstract

The 21Na(p,γ)22Mg reaction is an important link in the synthesis of 22Na in oxygenneon novae, and serves as one of the first steps of the rp-process in x-ray bursts. This reaction has recently been studied at the TRIUMF-ISAC radioactive beam facility with the new DRAGON recoil separator. Resonant contributions have been measured for seven 22Mg states, from near the proton threshold to about 6 MeV in excitation energy. We report the results and their impact on the 21Na(p,γ)22Mg reaction rate in novae and x-ray bursts. [Copyright &y& Elsevier]
