Radiative and correlation effects on the paritynonconserving transition amplitude in heavy alkalimetal atoms
Abstract
The complete gaugeinvariant set of the oneloop QED corrections to the paritynonconserving (PNC) amplitude in cesium and francium is evaluated to all orders in {alpha}Z using a local form of the DiracFock potential. The calculations are performed in both length and velocity gauges for the absorbed photon and the total binding QED correction is found to be 0.27(3)% for Cs and 0.28(5)% for Fr. Moreover, a highprecision calculation of the electroncorrelation and Breitinteraction effects on the 7s8s PNC amplitude in francium using a largescale configurationinteraction DiracFock method is performed. The obtained results are employed to improve the theoretical predictions for the PNC transition amplitude in Cs and Fr. Using an average value from two most accurate measurements of the vector transition polarizability, the weak charge of {sup 133}Cs is derived to amount to Q{sub W}=72.65(29){sub exp}(36){sub theor}. This value deviates by 1.1{sigma} from the prediction of the standard model. The values of the 7s8s PNC amplitude in {sup 223}Fr and {sup 210}Fr are obtained to be 15.49(15) and 14.16(14), respectively, in units of ix10{sup 11}(Q{sub W})/N a.u.

The matrix element of a bound electron interacting with the nucleus through exchange of a Z boson is studied for the gaugeinvariant case of 2s{sub 1/2}2p{sub 1/2} transitions in hydrogenic ions. The QED radiative correction to the matrix element, which is {alpha}/2{pi} in lowest order, is calculated to all orders in Z{alpha} using exact propagators. Previous calculations of the firstorder binding correction are confirmed both analytically and by fitting the exact function at low Z. Consequences for the interpretation of parity nonconservation in cesium are discussed.

It is widely believed that the standard model of particle physics is just an intermediate step in understanding the properties of the elementary physics in nature and the interactions between them. Over the past twenty years, studies of the parity nonconservation in atomic systems based on nonaccelerator methods have made remarkable progress. An experiment to measure parity nonconservation in singly ionized barium has been proposed as an independent test of the standard model. We have employed the relativistic coupledcluster theory to calculate the parity nonconserving 6s{sup 2}S{sub 1} at {sub {approx}}{sub sol{approx}} at {sub 2}{yields}5d{sup 2}D{sub 3} at {sub {approx}}{submore »

Calculation of paritynonconserving effects in the 6 /sup 2/P/sub 1/2/7 /sup 2/P/sub 1/2/ forbidden M1 transition in thallium
Calculations are presented of the E1 amplitude expected in the 6 /sup 2/P/sub 1/2/7 /sup 2/P/sub 1/2/ forbidden M1 transition in Tl if parity conservation is violated in the neutral weak eN interaction, as proposed in a number of gauge models, including that of Weinberg and Salam. Valenceelectron wave functions are generated as numerical solutions to the Dirac equation in a modified Tietz central potential. These wave functions are used to calculate allowed E1 oscillator strengths, hfs splittings, and Stark E1 transition amplitudes. These results are compared with experiment and the agreement is generally good. The relativistic 6 /sup 2/P/submore »
