Two simple ab initio methods based on one-electron wave functions are employed to calculate the singleelectron capture and single ionization of H 2 O and CO molecules by ion impact. The anisotropy of the molecular targets is taken into account by using multicenter pseudopotentials to represent the interaction of the active electron with the ionic molecular core. These two methods are applied to the study of three collisional systems: H + + H 2 O, He 2+ + H 2 O, and C 2+ + CO. Comparison with experiments and other theoretical works is presented when available.

Formation of Anti-Reflection Coating by Hydrothermal Treatment of Aluminum Films and Their Stabilization by Dehydration

Anti-reflection coating, which exhibits higher transmittance than that of glass substrate itself, has been obtained by hydrothermal treatment of Al film in ultrapure water and hydrothermally-treated Al film was consisted of transparent boehmite (aluminum oxyhydroxide) (J. Appl. Phys. 106 (2009) 023524). However the stability of the hydrothermally-treated film is not enough, as boehmite contains water in its crystal structure. In this study, we examined the heat-treatment of such boehmite film. According to transmission electron microscopy and transmission Fouriertransform infrared spectroscopy, dehydration was observed at above 673 K for 1 h and boehmite transformed to a stable phase of £-alumina. Though the structural change took place, the optical property of high transmittance remained and/or even improved.

Vibrational resonance in the Morse oscillator

2013

We investigate the occurrence of vibrational resonance in both classical and quantum mechanical Morse oscillators driven by a biharmonic force. The biharmonic force consists of two forces of widely different frequencies ω and Ω with Ω ≫ ω. In the damped and biharmonically driven classical Morse oscillator applying a theoretical approach we obtain an analytical expression for the response amplitude at the low-frequency ω. We identify the conditions on the parameters for the occurrence of the resonance. The system shows only one resonance and moreover at resonance the response amplitude is 1/(dω) where d is the coefficient of linear damping. When the amplitude of the high-frequency force is varied after resonance the response amplitude does not decay to zero but approaches a nonzero limiting value. We have observed that vibrational resonance occurs when the sinusoidal force is replaced by a square-wave force. We also report the occurrence of resonance and anti-resonance of transition probability of quantum mechanical Morse oscillator in the presence of the biharmonic external field. 46.40.Ff.
