Studying the violation of parity and time-reversal invariance in atomic systems has proven to
be a very effective means of testing the electroweak theory at low energy and searching for …

Light guided by an optical nanofibre has a very steep evanescent field gradient extending
from the fibre surface. This gradient can be exploited to drive electric quadrupole transitions …

We propose methods and present calculations that can be used to search for evidence of
cosmic fields by investigating the parity-violating effects, including parity nonconservation …

Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions,
we perform a detailed study of electric dipole (E 1) transition amplitudes in K, Ca+, Rb, Sr+ …

Using the inherent timing stability of pulses from a mode-locked laser, we measure the
cesium 6 P 3/2 excited-state lifetime. An initial pump pulse excites cesium atoms in two …

We report on our calculations of differential hyperfine anomalies in the nuclear single-
particle model for a number of atoms and ions of interest for precision atomic tests of the …

Doppler-free two-photon (DFTP) spectroscopy is a standard technique for precision
measurement of transition frequencies of dipole-forbidden transitions. Here, we report the …

We find very good agreement between our theoretically evaluated lifetimes of the 5 d 2 D 3/2
and 5 d 2 D 5/2 states of Cs with the experimental values reported by DiBerardino et …

Lifetimes of the 6 d D 3/2 2 and 6 d D 5/2 2 states in Fr are determined from calculations of
the radiative transition amplitudes of the allowed electric dipole (E 1) and the forbidden …

This article presents detailed experimental and theoretical studies of the satellite
fluorescence lines observed when the $5 P_ {3/2}\to 6P_J $,($ J= 1/2$, $3/2$) electric …
