Investigation into the properties and structure of unstable nuclei far from stability is a key
avenue of research in modern nuclear physics. These efforts are motivated by the continual …

This review describes the methods of trapping cold atoms in electromagnetic fields and in
the combined electromagnetic and gravity fields. We discuss first the basic types of the …

Optical experiments have demonstrated cases in which mirror symmetry in stable atoms is
broken during the absorption or emission of light. Such results, which are in conflict with …

Efficient collection of atoms into a vapor-cell laser trap requires a special wall material for the
cell that minimizes the interactions between the vapor and the wall. Tests of several different …

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 …

We have efficiently loaded a vapor cell magneto-optical trap from an orthotropic source of
221 Fr with a trapping efficiency of 56 (10)%. A novel detection scheme allowed us to …

An overview is given on the application of lasers in nuclear physics. The review focuses on
atomic physics techniques for extracting nuclear properties such as the nuclear spin, the …

We review the use of laser cooling and trapping for Standard Model tests, focusing on
trapping of radioactive isotopes. Experiments with neutral atoms trapped using modern laser …

Francium is a candidate for atomic parity non-conservation (PNC) experiments. Its simple
atomic structure has been the subject of extensive experimental research facilitated by the …

A magneto-optic trap (MOT) can provide a well-polarized, backing-free, localized source of
radioactive atoms for β-decay experiments. We have trapped approximately 6000 atoms of …
