“…This result is in agreement with the known spin of 19SAu and a large contribution to the thermal-capture cross section from the 2 + resonance at 4.9eV. The circular polarization value of the ground-state transition of 6513 keV gives the more precise value c~y = 1.00 (1). Using the angular distribution data of the ground-state transition the following values are derived Table 1.…”

“…In s-wave capture this can be in any direction with respect to the beam. In expression (1) Ndt is the thickness of a layer of the target in nuclei/era 2, %, is the capture cross section for the unpolarized case, ~b, is the neutron flux, F~ is the partial radiation width for a primary gamma transition, Fro t is the total radiation width, S o is the detection efficiency, and Qk is the usual solid-angle attenuation factor. Expression (1) gives the detected intensity in a solid angle dO of gamma radiation for a thin target, that is if N~o,dt~l.…”

The 197Au(n,?) reaction was studied with the aid of polarized thermal neutron beams. Two kinds of experimental data were obtained: i) circular polarization of gamma rays of high energy due to capture of polarized neutrons by unoriented 197Au nuclei, and ii) angular distribution of such gamma rays observed after capture of polarized neutrons by polarized 197Au nuclei. Spins of several levels of 198Au could be uniquely assigned or could be restricted. The sign of the hyperfine field of Au in AuFe has been determined to be negative.
