| Abstract: | The weak neutral current results in a parity-violating one-pion-exchange potential in nuclei. A search for this force has been carried out with the 1081 keV γ-radiation of 18F, which is expected to be circularly polarized. Excited 18F nuclei were produced with the 16O(3He, p)18F reaction and the γ-ray polarization was measured with a multiple transmission polarimeter system. The experimental result P = (− 1.0 ± 1.8) × 10−3 is smaller than recent theoretical estimates. |
