The final result is \u003c7s,F=5\n||d_PNC|| 7s,F=4\u003e = -0.49 10^{-10} i kappa a.u., where kappa is the\ndimensionless coupling constant. This is approximately an order of magnitude\nlarger than similar amplitude in Cs. The dominant contribution to kappa is\nassociated with the anapole moment of the nucleus.",
