Parity non-conservation in thallium
M G Kozlov, S G Porsev, W R Johnson
We report a new calculation of the parity non-conserving E1 amplitude for the 6p_{1/2} -> 6p_{3/2} transition in Tl. Our result for the reduced matrix element is $E1_{PNC}=-(66.7 \…

Breit interaction in heavy atoms
M. G. Kozlov, S. G. Porsev, I. I. Tupitsyn
In this letter we discuss how to include Breit interaction in calculations of low-energy properties of heavy atoms in accurate and effective way. In order to illustrate our approac…
