Scattering matrix pole expansions for complex wavenumbers in -matrix theory
Pablo Ducru, Vladimir Sobes, Gerald Hale +2
In this follow-up article to [Shadow poles in the alternative parametrization of R-matrix theory, Ducru (2020)], we establish new results on scattering matrix pole expansions for c…

Shadow poles in Brune parametrization of R-matrix theory
Pablo Ducru, Vladimir Sobes, Benoit Forget +2
Our collective knowledge of nuclear cross sections is recorded as resonance parameters in nuclear data libraries. To evaluate these parameters, campaigns of measurements are fitted…

Scattering matrix pole expansions & invariance with respect to R-matrix parameters
Pablo Ducru, Vladimir Sobes, Gerald Hale +2
Nuclear data libraries (ENDF, JEFF, JENDL, CENDL, etc.) document our phenomenological knowledge of nuclear cross sections as interpreted by R-matrix theory. The R-matrix scattering…
