C 103, 064610 (2021) P.Ducru, A.Alhajri, I.Meyer, B.Forget, V.Sobes, C.Josey, J.Liang Windowed multipole representation of R-matrix cross sections NUCLEAR REACTIONS 134Xe(n, X), E=2186.0, 6315.0 eV p-wave resonances; 238U(n, X), E=6.67428 eV resonance; analyzed and derived the windowed multipole representation of nuclear cross sections through physical and mathematical equivalents to R-matrix cross sections, with the inclusion on temperature treatment of angle-integrated cross sections, and Doppler broadening as the averaging of cross sections over the thermal motion of the target atoms, and important in neutron transport applications such as stability of many nuclear reactors with negative thermal reactivity. Discussed collaborative effort to establish a new nuclear cross-section library format the Windowed Multipole Library representing R-matrix cross sections constructed by finding the poles of the Kapur-Peierls operator and performing Hwang's conjugate continuation, thus connecting the windowed multipole representation to both the Bloch and Wigner-Eisenbud R-matrix theory and to the Humblet-Rosenfeld pole expansions in wave-number space. See also preceding 2021Du11 and 2021Du12 articles by three of the same authors about shadow poles in the alternative parametrization and scattering matrix pole expansions in R-matrix theory.
