Neutron capture and transmission measurements were carried out from thermal to 2000 eV on both solid and liquid samples containing elemental cesium (133Cs). This work describes the extension of the R-matrix analysis of these data from 600 to 2000 eV by correcting the capture data for false capture in the NaI detector. These false capture–corrected capture and transmission data were analyzed for resonance parameters utilizing the SAMMY Bayesian analysis code to simultaneously fit both the capture and transmission data. Parameters were obtained for 53 cesium resonances over the 600- to 2000-eV energy range. The s-wave strength function was determined over the energy range from 0 to 1800 eV for both spin J = 3 and J = 4 resonances.
