This handbook is designed to provide a selection of the most important and frequently used
atomic spectroscopic data in an easily accessible compact format. The compilation includes …

Structural, elastic, electronic, optical and thermoelectric properties of fluoroperovskites AGeF
3 (A= K, Rb, and Fr) have been investigated using Density Functional Theory (DFT) …

Two-component and scalar relativistic energy-consistent pseudopotentials for the group 1
elements from K to element 119 are presented using nine electrons for the valence space …

The spectroscopic hyperfine constants for all the alkali atoms are reported. For atoms from
lithium to cesium, only the long lived atomic isotopes are examined. For francium, the …

The periodic table provides a deep unifying principle for understanding chemical behaviour
by relating the properties of different elements. For those belonging to the fifth and earlier …

We have performed ab initio mixed-states and sum-over-states calculations of parity-
nonconserving (PNC) electric dipole (E 1) transition amplitudes between s− d electron states …

An overview of experimental data and theoretical methods is given for charge-changing
processes with ion beams passing through gaseous, solid, and plasma targets. The main …

We present lifetime measurements of the 7 p 2 P 3/2 and 7 p 2 P 1/2 levels of Fr. We use a
time-correlated single-photon counting technique on a cold sample of 210 Fr atoms in a …

The alkali element francium has no stable isotopes and has eluded extensive study because
sufficient quantities have not been available for detailed investigations. More than 1000 210 …

The complete gauge-invariant set of the one-loop QED corrections to the parity-
nonconserving (PNC) amplitude in cesium and francium is evaluated to all orders in α Z …
