Helium nanodroplets doped with polar molecules are studied by electrostatic deflection. This broadly applicable method allows even polyatomic molecules to attain sub-Kelvin temperatures and nearly full orientation in the field. The resulting intense

Electrostatic deflection of a molecular beam of massive neutral particles: Fully field-oriented polar molecules within superfluid nanodroplets

Autor: Merthe, Daniel J., Kresin, Vitaly V.

Publikováno v: J. Phys. Chem. Lett. v. 7, p. 4879 (2016)

Electric deflection measurements on liquid helium nanodroplets doped with individual polar molecules demonstrate that the cold superfluid matrix enables full orientation of the molecular dipole along the external field. This translates into a deflect

A Sampling Theorem for Computational Diffraction

Autor: Merthe, Daniel J.

A major challenge of many diffraction calculations, using some form of the Rayleigh-Sommerfeld formulas, is the integration of a highly oscillatory integrand. Here we derive a potentially useful alternative form of solution to the Helmholtz equation,

The Advanced Light Source (ALS) beamline (BL) 10.3.2 is an apparatus for X-ray microprobe spectroscopy and diffraction experiments, operating in the energy range 2.4-17 keV. The performance of the beamline, namely the spatial and energy resolutions o

Convenience and cost often lead to synchrotron beamlines where the final Kirkpatrick-Baez (KB) focusing pair must relay the final image to different samples at different image distances [Proc. FEL2009, 246-249 (2009)], either for different experiment
