-matrix type parametrization of the Jost function for extracting the resonance parameters from scattering data
P. Vaandrager, M. L. Lekala, S. A. Rakityansky
A new method is proposed for fitting non-relativistic binary-scattering data and for extracting the parameters of possible quantum resonances in the compound system that is formed…

The Jost function and Siegert pseudostates from R-matrix calculations at complex wavenumbers
Paul Vaandrager, Jérémy Dohet-Eraly, Jean-Marc Sparenberg
The single-channel Jost function is calculated with the computational R-matrix on a Lagrange-Jacobi mesh, in order to study its behaviour at complex wavenumbers. Three potentials d…

Extracting the resonance parameters from experimental data on scattering of charged particles
P. Vaandrager, S. A. Rakityansky
A new parametrization of the multi-channel S-matrix is used to fit scattering data and then to locate the resonances as its poles. The S-matrix is written in terms of the correspon…
