Breit interaction and parity nonconservation in many-electron atoms
Breit interaction and parity nonconservation in many-electron atoms
We present accurate ab initio nonperturbative calculations of the Breit correction to the parity nonconserving (PNC) amplitudes of the $6s\text{\ensuremath{-}}7s$ and $6s\text{\ensuremath{-}}5{d}_{3โ2}$ transitions in Cs, $7s\text{\ensuremath{-}}8s$ and $7s\text{\ensuremath{-}}6{d}_{3โ2}$ transitions in Fr, $6s\text{\ensuremath{-}}5{d}_{3โ2}$ transition in ${\mathrm{Ba}}^{+}$, $7s\text{\ensuremath{-}}6{d}_{3โ2}$ transition in ${\mathrm{Ra}}^{+}$, and $6{p}_{1โ2}\text{\ensuremath{-}}6{p}_{3โ2}$ transition in Tl. The results for the $6s\text{\ensuremath{-}}7s$ transition โฆ
