摘要: Parity non-conserving (PNC) E1 amplitudes for 205Tl are calculated. In units of 10-10 (i mod e aBQw/-N) (Qw is the weak charge nucleus, N number neutrons) authors find that (6p3/2 1/2 Dz 6p1/2 1/2)=-2.70(1+or-0.03) and (7p1/2 1/2)=-0.79(1+or-0.06). Using technique developed recalculate PNC amplitude 133Cs, finding, with a high degree accuracy, (7s 6s 1/2)=0.090(1+or-0.02). They also calculate 85Rb, obtaining (6s 5s 1/2)=0.0139(1+or-0.02). For calculation they use time-dependent Hartree-Fock method as first approximation then take into account all correlation corrections second order in residual Coulomb interaction.
