Isotopic variation of parity violation in atomic ytterbium

, 2018
We report on measurements of atomic parity violation, made on a chain of ytterbium isotopes with mass numbers A=170, 172, 174, and 176. In the experiment, we optically excite the 6s2 1S0 -> 5d6s 3D1 transition in a region of crossed electric and magnetic

Measurement of the hyperfine splitting of the 6S$_{1/2}$ level in rubidium [PDF]

, 2008
We present a measurement of the hyperfine splitting of the 6S$_{1/2}$ excited level of rubidium using two photon absorption spectroscopy in a glass cell. The values we obtain for the magnetic dipole constant A are 239.18(03) MHz and 807.66(08) MHz for $^{

Hanford Isotope Project strategic business analysis Cesium-137 (Cs-137) [PDF]

, 1995
The purpose of this business analysis is to address the beneficial reuse of Cesium 137 (Cs-137) in order to utilize a valuable national asset and possibly save millions of tax dollars. Food irradiation is the front runner application along with other uses.

A target for production of radioxenons [PDF]

A liquid cesium target has been developed which allows the production and separate identification of the neutron deficient isotopes of xenon. The present report describes irradiations utilizing 34 to 41 MeV protons to produce millicurie quantities of Xe ...

Mixture of ultracold lithium and cesium atoms in an optical dipole trap

, 2001
We present the first simultaneous trapping of two different ultracold atomic species in a conservative trap. Lithium and cesium atoms are stored in an optical dipole trap formed by the focus of a CO$_2$ laser. Techniques for loading both species of atoms

An Atomic Linear Stark Shift Violating P But Not T Arising From the Electroweak Nuclear Anapole Moment [PDF]

, 2001
We propose a direct method of detection of the nuclear anapole moment. It is based on the existence of a linear Stark shift for alkali atoms in their ground state perturbed by a quadrupolar interaction potential and a magnetic field.

Standard Model tests with trapped radioactive atoms

, 2009
We review the use of laser cooling and trapping for Standard Model tests, focusing on trapping of radioactive isotopes. Experiments with neutral atoms trapped with modern laser cooling techniques are testing several basic predictions of electroweak ...

Observation and absolute frequency measurements of the 1S0 - 3P0 optical clock transition in ytterbium [PDF]

, 2005
We report the direct excitation of the highly forbidden (6s^2) 1S0 - (6s6p) 3P0 optical transition in two odd isotopes of ytterbium. As the excitation laser frequency is scanned, absorption is detected by monitoring the depletion from an atomic cloud at ~

Fission-Residues Produced in the Spallation Reaction 238U+p at 1 A GeV

, 2003
Fission fragments from 1 A GeV 238U projectiles irradiating a hydrogen target were investigated by using the fragment separator FRS for magnetic selection of reaction products including ray-tracing and DE-ToF techniques.
