• Neutron transmission measurements on <SUP>59</SUP>Co 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 <SUP>59</SUP>Co 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.<BR>The following results were obtained, <I>E</I><SUB>0</SUB>= 132.0± 0.5 eV, <I>Γ</I> = 6.0± 0.2 eV, <I>Γ</I> n•5.15± 0.06eVand <I>J</I>=4. The value of the potential scattering radius, obtained from the transmission of the thickest sample, was <I>R</I>'= 5.3± 0.5 fm.
