“…The atoms were collimated into an atomic beam feeding a vapor-cell lined with silicone polymer coatings to which the alkali atoms do not stick [41,42]. The vapor cell confined the atoms for many passes through the beams and many chances to be trapped, after re-thermalization upon contact with the walls replenished the low-velocity tail of the Maxwell-Boltzmann velocity distribution [43].…”

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 cooling techniques are testing several basic predictions of electroweak unification. For nuclear β decay, demonstrated trap techniques include neutrino momentum measurements from beta-recoil coincidences, along with methods to produce highly polarized samples. These techniques have set the best general constraints on non-Standard Model scalar interactions in the first generation of particles. They also have the promise to test whether parity symmetry is maximally violated, to search for tensor interactions, and to search for new sources of time reversal violation. There are also possibilites for exotic particle searches. Measurements of the strength of the weak neutral current can be assisted by precision atomic experiments using traps loaded with small numbers of radioactive atoms, and sensitivity to possible time-reversal violating electric dipole moments can be improved.

We review the use of laser cooling and trapping techniques for nuclear betadecay angular correlations. Coincidences between the beta (β) and recoiling nucleus allow the determination of the neutrino (ν) momentum more directly than previously possible. Highly spin-polarized samples are also possible, with polarization known from atomic observables, and the nuclear recoils both in singles and in coincidence with the β add interesting observables. Ongoing experiments are trapping elements that provide pure Fermi, pure Gamow-Teller, and mixed Gamow-Teller transitions to distinguish sources of new physics. To compete with the next generation of neutron β-decay experiments, cases are being carefully chosen to minimize or at least know recoil-order corrections.
