This chapter discusses the principles and experimental methods for the detection of metastable—that is, long-lived, electronically excited—atoms and molecules. The discussion will focus on neutral metastable particles at low kinetic energies (<1 eV), for which the key properties governing detection ...
The ion source employs a first gas that is passed through an electrical discharge to produce metastable gas molecules as well as charged particles of various kinds. Ions and other charged particles are removed from the first gas which is then reacted with a second gas having a lower ionization...
This process also fully shows that the oxygen molecules have completely penetrated into the liquid metal, and the entire liquid metal structure is paste-like and loses its flow characteristics. Gallium oxides are divided into metastable gallium oxide (Ga2O) and stable gallium trioxide (Ga2O3). ...
Quenching cross sections for electronic energy transfer reactions between metastable argon atoms and noble gases and small molecules Reaction rate constants for the quenching of electronic energy in metastable argon (3P0,2) by Kr, Xe, and a number of simple molecules have been measured. ... LG ...
A“mass spectrometer” is an analyzer used in chemical analysis that operates by ionizing atoms or molecules and then measuring the relative mass of the ionized products. Mass spectrometry (“MS”) is routinely used to measure the molecular weight of a sample molecule, as well as the fragmentati...
State-selective detection of near-dissociation ultracold KRb X {sup 1}{sigma}{sup +} and a {sup 3}{sigma}{sup +} molecules We report on the state-selective detection of near-dissociation ultracold KRb molecules in the ground X {sup 1}{sigma}{sup +} state and the metastable a {s.....
If a minute quantity of other gases and vapors exists, the metastable argon atoms can transfer their energies to these gases and vapors, leading to their ionization when the potential of the metastable atom is higher than the ionization potentials of the gas or vapor molecules. By measuring the...
17. Previous research has mainly focused on controlling the nucleation kinetics by ligand molecules18,19, low-temperature gradient20, or liquid diffusion21, which do not remarkably contribute to the following growth step. In essence, crystal growth is undoubtedly related to the mass transfer and ...
