Parity non-conservation in thallium and caesium

Abstract
Parity non-conserving (PNC) El-amplitudes for 205Tl are calculated: 7p1/2|Dz|6p1/2 = −7.9(1 ± 0.06), 6p3/2|Dz|6p1/2 = −27.0(1 ± 0.03) (in units of 10-11i|e|aB(−Qw/N)), Qw is the weak charge of the nucleus, N = 124 is the number of the neutrons). Using the developed technique we recalculate the PNC El-amplitude for 133Cs with high accuracy: 7s|Dz|6s = 0.90(1 ± 0.02). The method of calculation is the time-dependent Hartree-Fock (TDHF) plus correlation corrections of second order in residual interaction.
