Abstract
Neutron transmission measurements on 59Co have been made for neutron energies from 0.8 eV to 3 keV using the time-of-flight spectrometer of a linear accelerator at the Japan Atomic Energy Research Institute. The maximum time resolution was 10 nsec/m. Resonance parameters of the 132-eV resonance of 59Co were determined from the neutron transmissions of several samples of different thicknesses by the thick-thin method, using an area analysis method based on the Breit-Wigner single-level formula.
The following results were obtained, E0= 132.0± 0.5 eV, Γ = 6.0± 0.2 eV, Γ n•5.15± 0.06eVand J=4. The value of the potential scattering radius, obtained from the transmission of the thickest sample, was R'= 5.3± 0.5 fm.
