Calculation of parity-nonconserving optical rotation in iodine at 1315 nm

We examine the feasibility of a parity nonconserving (PNC) optical rotation experiment for the P3/2 → P1/2 transition of atomic iodine at 1315 nm. The calculated E1PNC to M1 amplitude ratio is R = 0.80(16) × 10−8. We show that very large PNC rotations (greater than 10 μrad) are obtained for iodine-atom column densities of ∼1022 cm−2, which can be produced by increasing the effective interaction...

High-precision calculation of the parity-nonconserving amplitude in francium

A high-precision calculation of the 7s-8s parity-nonconserving ~PNC! transition amplitude in francium, based on a relativistic all-order method, is presented. Our values for the PNC amplitudes in Fr and Fr are EPNC515.41(17) and 14.02(15), respectively, in units 10 iueua0(2QW /N), where QW is the weak charge and N is the neutron number. Spin-dependent contributions to the PNC amplitude are calc...

Parity Nonconserving Current in Conductors of Electricity

The effects due to the weak interaction between the conduction electrons and the lattice nuclei in external magnetic field are considered. It is shown that the continuous current arises under the influence of the rotating magnetic field.

3260 High - Accuracy Calculation of 6 s ! 7 s Parity - Nonconserving Amplitude in Cs

I. I. Tupitsyn Institute of Physics, St. Petersburg State University, Uljanovskaya 1, Petrodvorets, 198504 St. Petersburg, Russia (Received 9 January 2001) We calculated the parity-nonconserving (PNC) 6s ! 7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude b are...
