It was recently shown that the exact factorization of the electron-nuclear wave function allows the construction of a Schrödinger equation for the electronic system, in which the potential contains exactly the effect of coupling to the nuclear degrees of freedom and any external fields. Here we study the exact potential acting on the electron in charge-resonance enhanced ionization in a model o...

Strutinsky shell corrections for the Cesium-coated fullerenes were investigated. The single particle levels of electrons are obtained using the spherical mean-field potential of a shifted Wood-Saxon type. The parameters of the potential are adjusted to reproduce the experimental ionization energies of the Cs(N) clusters and the magic numbers observed in their photo-ionization spectra of the C60...

With the aim of exploring the electronic and optical properties of some interesting conductive copolymers in view of potential applications, a regular oligomer systems made of aniline and three reference heterocyclic compounds (pyrrole, thiophene and furan) are studied using density functional theory (DFT) and time dependent density functional theory (TDDFT) calculations at B3LYP/6-31+G(d,p) le...

We present a further development of an analytical model for the tunneling ionization of atoms by a lowfrequency laser field of an arbitrary strength, including the strong-field region. The model uses a very accurate approximation of the true ionization barrier/potential in the Schrödinger equation by the effective parabolic barrier/ potential-based on the algorithm suggested by Miller and Good ...

Using time-dependent density functional theory (TDDFT) calculations, we compare tunneling ionization of the a 4F ground state and the a 6D first excited state of vanadium in laser fields of intensities between 1.4 and 4.0 × 1013 W cm−2. The calculated ionization yields of the ground state of vanadium were already shown to agree well with experimental results [Chu and Groenenboom, Phys. Rev. A 9...

Field ionization energy spectra of toluene, cycloheptatriene and phenolare reported. Details of the spectra are correlated with molecular proper-ties. The implications of the observation for analytical work are discussed. INTRODUCTIONField Ionization has proven to be a useful tool in the mass spectrometricstudy of organic molecules. This paper presents data which suggest tec...

introduction computed tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. materials and methods two refe...

An inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. The experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced...
