Description
The neutron capture cross section of 137Ba has been measured to high resolution (ΔE/E approximately equal to 0.2%) below Esub(n) = 60 keV. Average values of resonance parameters, extracted for resonances in the range 2.7 < Esub(n) < 12 keV, are as follows: s-wave level spacing = 380 +- 70 eV; s-wave radiative width sub(s) = 80 +- 15 MeV; s-wave neutron strength function 104 Ssub(o) = 0.57 +- 0.2; and p-wave neutron strength function 104 Ssub(l) = 0.45 +- 0.2. The s-wave radiative width and the s-wave neutron strength function appear to be lower for 137Ba than for the other barium isotopes. (author)
