We report the photodissociation of laboratory oriented OCS molecules. A molecular beam of OCS molecules is hexapole state-selected and spatially oriented in the electric field of a velocity map imaging lens. The oriented OCS molecules are dissociated at 230 nm with the linear polarization set at 45 degrees to the orientation direction of the OCS molecules. The CO(nu=0,J) photofragments are quan...

In this note we discuss a technique for definin”g the geometry of ~:$ipole antenna such that low-frequency parameters of the antenna, such as capacitance and mean charge separat~on distance, are readily calculable. This technique involves the assumption of an appropriate static charge distribution which we call an equivalent-charge distribution. Calculating the potential distribution from the e...

Spherical Janus colloids, particles with different surface properties on their two hemispheres, are generally heterogeneous in permittivity. This dielectric heterogeneity may affect their behavior in electrolytes and external electric fields, but is typically not taken into account in computational studies. We apply the iterative dielectric solver developed by Barros and Luijten [Phys. Rev. Let...

Focusing of molecular beams using an electrostatic hexapole is a mature technique to produce samples of state-selected molecules. The ability to efficiently focus molecules depends on the properties of the molecular species of interest, the length of the hexapole state selector, as well as on the maximum electric field strength that can be achieved in these devices. In particular for species wi...

This paper is a theoretical work in support of a newly proposed experiment R. Stutz and E. Cornell, Bull. Am. Soc. Phys. 89, 76 2004 that promises greater sensitivity to measurements of the electron’s electric dipole moment EDM based on the trapping of molecular ions. Such an experiment requires the choice of a suitable molecule that is both experimentally feasible and possesses an expectation ...

Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric dipole moment in terms of supersymmetric phases, and to radiative flavor changing lepton decays in terms of small violations of slepton universal...

The authors measure the hyperfine coupling constant, molecular frame electric dipole moment, and magnetic $g$-factor of ThF${}^{+}$ compare them with theoretical calculations. results imply that could potentially be an excellent candidate for electron-electric-dipole-moment experiments due to its longer coherence time than HfF${}^{+}$, which in a higher sensitivity.

We recently reported a new measurement of the electron’s electric dipole moment using YbF molecules (Hudson et al 2011 Nature 473 493). Here, we give a more detailed description of the methods used to make this measurement, along with a fuller analysis of the data. We show how our methods isolate the electric dipole moment from imperfections in the experiment that might mimic it. We describe th...
