The Nature of Weak MgII Absorbing Structures [PDF]
Astrophys.J.641:190-209,2006, 2005 We consider geometries and possible physical models for weak low ionization absorbers based on the relative incidence of low and high ionization absorption systems. We found a total of 16 metal-line systems, with low and/or high ionization absorption detected in our survey of weak low ionization absorption systems from the archive of HST/STIS data. The

Current-voltage characteristic of parallel-plane ionization chamber with inhomogeneous ionization [PDF]
JINST2:P08007,2007, 2007 The balances of particles and charges in the volume of parallel-plane ionization chamber are considered. Differential equations describing the distribution of current densities in the chamber volume are obtained. As a result of the differential equations solution an analytical form of the current-voltage characteristic of parallel-plane ionization ...

Elliptical Polarization and Probability of Double Ionization [PDF]
Phys. Rev. Lett. 105, 083001 (2010), 2010 The degree of elliptical polarization of intense short laser pulses is shown to be related to the timing of strong-field non-sequential double ionization. Higher ellipticity is predicted to force the initiation of double ionization into a narrower time window, and this "pins" the ionizing field strength in an unexpected way, leading to the first ...

Ionization and Attachment Coefficients in C4F7N Gas Measured by the Steady-State Townsend Method
Applied Sciences, 2019 The normalized Townsend first ionization coefficient α/N and normalized attachment coefficient η/N in pure C4F7N were measured by using the steady-state Townsend (SST) method for a range of reduced electric fields E/N from 750 to 1150 Td at room ...

Classical Theory of High Field Atomic Ionization Using Elliptical Polarization [PDF]
Phys. Rev. A 86, 013421 (2012), 2012 Important information about strong-field atomic or molecular ionization can be missed when using linearly polarized laser fields. The field strength at which an electron was ionized, or the time during a pulse of the ionization event are examples of such missing information.

Interaction of Be4+ and Ground State Hydrogen Atom—Classical Treatment of the Collision
Atoms, 2020 The interaction between Be4+ and hydrogen atom is studied using the three-body classical trajectory Monte Carlo method (CTMC) and the quasiclassical trajectory Monte Carlo method of Kirschbaum and Wilets (QTMC-KW).

Mechanistic investigation of ionization suppression in electrospray ionization
Journal of the American Society for Mass Spectrometry, 2000 We show results from experiments designed to determine the relative importance of gas phase processes and solution phase processes into ionization suppression observed in biological sample extracts. The data indicate that gas phase reactions leading to the loss of net charge on the analyte is not likely to be the most important process involved in ...

Ionization Cross Sections in the Collision between Two Ground State Hydrogen Atoms at Low Energies
Atoms, 2020 The interaction between two ground state hydrogen atoms in a collision was studied using the four-body classical trajectory Monte Carlo method. We present the total cross sections for the dominant channels, namely for the single ionization of the target,
