摘要
We present first a computation of the nuclear anapole moment of thallium by a method developed previously by the authors. Then we perform a detailed analysis of the spin dependent parity violating electron-nucleon potential generated by the hyperfine coupling perturbation upon the pseudoscalar interaction of the electron with the weak charge of the nucleus. This effect is found to be of order alpha-G(F)A2/3 and represents, depending upon the nucleus, (10-70)% of the anapole moment contribution. In the case of thallium, it compensates almost exactly the contribution associated with the axial hadronic neutral current. This fact, together with other arguments given in the paper, makes thallium a favoured candidate for the anapole moment search provided accurate enough experiments can be performed.
