Cooling of molecular ion beams [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004 An overview of the use of stored ion beams and phase space cooling (electron cooling) is given for the field of molecular physics. Emphasis is given to interactions between molecular ions and electrons studied in the electron cooler: dissociative recombination and, for internally excited molecular ions, electron-induced ro-vibrational cooling ...

High Sensitivity Broadband Transient Absorption Spectroscopy Of Molecular Beams [PDF]
, 2021 Molecules with ultrafast dynamics inherently have broad spectral features and modeling ultrafast spectroscopy data is a complex art. The complexity is reduced in the gas phase, however most ultrafast spectroscopies are limited to high-density samples ...

A compact molecular beam machine [PDF]
Review of Scientific Instruments, 2009 We have developed a compact, low cost, modular, crossed molecular beam machine. The new apparatus utilizes several technological advancements in molecular beams valves, ion detection, and vacuum pumping to reduce the size, cost, and complexity of a molecular beam apparatus.

DECAY DYNAMICS IN MOLECULAR BEAMS [PDF]
Mass Spectrometry Reviews, 2020 The phenomenon of power law decays in molecular beams is reviewed. The transition from a canonical to a microcanonical description of the decay is analyzed, and the appearance of the power law decay derived. Deviations from a power law often contain information on parallel competing processes.

Molecular beams with a tunable velocity [PDF]
Physical Chemistry Chemical Physics, 2006 The merging of molecular beam methods with those of accelerator physics has yielded new tools to manipulate the motion of molecules. Over the last few years, decelerators, lenses, bunchers, traps, and storage rings for neutral molecules have been demonstrated. Molecular beams with a tunable velocity and with a tunable width of the velocity distribution

Molecular beam epitaxy of KTaO3
Journal of Vacuum Science & Technology A, 2023 Strain-engineering is a powerful means to tune the polar, structural, and electronic instabilities of incipient ferroelectrics. KTaO3 is near a polar instability and shows anisotropic superconductivity in electron-doped samples. Here, we demonstrate growth of high-quality KTaO3 thin films by molecular-beam epitaxy.
