Description
Neutron transmission measurements were carried out on the separated isotopes of Ba at the JAERI electron linac. Resonance energies and neutron widths were determined for a large number of resonances in the neutron energy range from 400 eV to 4.6 keV for 135Ba, 15 keV for 137Ba and 63 keV for 138Ba. Many of these resonances were newly observed in this experiment. The s-wave strength functions obtained are S0 = (1.33 ±0.22) x 10-4 for 135Ba, and S0 = (0.51 ±0.12) x 10-4 for 137Ba. An apparent energy dependence of the strength function was observed for 135Ba. New resonance parameters of 138Ba were also obtained for several weak p-wave levels. (author)
