Abstract

Many-body calculation of nuclear spin-dependent parity-nonconserving amplitude for 7s,F=\stackrel\ensuremath→47s,F=5 transition between hyperfine sublevels of the ground state of ²¹¹Fr is carried out. The final result is 〈7s,F=5||d_PNC||7s,F=4〉=\ensuremath-0.49\ifmmode×\else\texttimes\fi10^\ensuremath-10i\ensuremathκ a.u., where \ensuremathκ is the dimensionless coupling constant. This is approximately an order of magnitude larger than similar amplitude in Cs. The dominant contribution to \ensuremathκ is associated with the anapole moment of the nucleus.
