High-resolution molecular spectroscopy is a sensitive probe for violations of fundamental
symmetries. Symmetry violation searches often require, or are enhanced by, the application …

Static dipole polarizabilities are calculated in the ground and metastable states of Sr+, Ba+
and Ra+ using the relativistic coupled-cluster method. Trends of the electron correlation …

A single Ra+ ion stored in a Paul radio frequency ion trap has excellent potential for a
precision measurement of the electroweak mixing angle at low momentum transfer and as …

A single trapped Ra+(Z= 88) ion provides a very promising route towards a most precise
measurement of Atomic Parity Violation (APV), since APV effects grow faster than Z 3. This …

As an important step toward an atomic parity violation experiment in one single trapped Ra+
ion, laser spectroscopy on short-lived Ra 212, 213, 214+ ions was conducted. The isotope …

Energy levels, wavelengths, lifetimes, and hyperfine structure constants for the isotopes of
the first and second spectra of radium, Ra I and Ra II, have been compiled. Wavelengths …

The international workshop on “Application of Lasers and Storage Devices in Atomic Nuclei
Research” held during 2009 in Poznan gave an excellent overview on the latest …

Atomic parity violation (APV) experiments are sensitive probes of the electroweak interaction
at low energy. These experiments are competitive with and complementary to high-energy …

We explore the potential of the electric quadrupole transitions 7 s 2 S 1/2-6 d 2 D 3/2, 6 d 2 D
5/2 in radium isotopes as single-ion optical frequency standards. The frequency shifts of the …

Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed.
The isotope shifts of the 6 d 2 D 3/2–7 p 2 P 1/2 transition in 209− 214 Ra+, which are …
