The cross section of the 147Sm(n,a) reaction was measured from 3 eV to 500 keY at ORELA in the frame of an ORNL-FLNP collaboration. Total a-particle widths of 104 resolved neutron resonances with spin J" = 3' or J" = 4' were measured in the energy interval 3 eV-700 eV. A statistical analysis of a-particle widths of the resonances was carried out for each spin state. Deviations of the a-width distributions from statistical theory are discussed. A detailed discussion is devoted to a specific resonance (or doublet) at Eo = 184 eV having an unusual a-particle spectrum and unusually large a-particle and neutron widths.
