R-Matrix description of particle energy spectra produced by low-energy T+T reactions
C. R. Brune, J. A. Caggiano, D. B. Sayre +3
An R-matrix model for three-body final states is presented and applied to a recent measurement of the neutron energy spectrum from the T+T->2n+alpha reaction. The calculation inclu…
Effective field theory as a limit of R-matrix theory for light nuclear reactions
Gerald M. Hale, Lowell S. Brown, Mark W. Paris
We study the zero channel radius limit of Wigner's R-matrix theory for two cases, and show that it corresponds to non-relativistic effective quantum field theory. We begin with the…
R-matrix analysis of reactions in the 9B compound system
Mark W. Paris, Gerald M. Hale, Anna C. Hayes-Sterbenz +1
Recent activity in solving the 'lithium problem' in big bang nucleosynthesis has focused on the role that putative resonances may play in resonance-enhanced destruction of 7Li. Par…
Functional reduction of the S matrix in the canonical formalism
Mark W. Paris
The Low equation is derived in a functional approach to the reduction of the S matrix in the canonical formalism. This establishes the vacuum expectation value of the scattering ma…
Effect of Sigma-beam Asymmetry Data on Fits to Single Pion Photoproduction off Neutron
I. I. Strakovsky, R. A. Arndt, W. J. Briscoe +2
We investigate the influence of new GRAAL Sigma-beam asymmetry measurements on the neutron in multipole fits to the single-pion photoproduction database. Results are compared to th…
Comparing partial-wave amplitude parametrization with dynamical models of meson-nucleon scattering
Mark W. Paris, Ron L. Workman
Relationships between partial-wave amplitude parametrizations, in particular the Chew-Mandelstam approach, and dynamical coupled-channel models are established and investigated. A…
