Transversely excited atmospheric CO2 laser-induced damage of TiN and (Ti,Al)N coatings
(Applied Surface Science, 1999)
When an energy-carrying beam strikes a solid surface, the surface is sputtered and many effects on the atomic, microscopic and macroscopic scale can be observed. The morphological changes induced on solid surfaces, the ...
User-friendly Monte Carlo program for the generation of gamma-ray spectral responses in complex source-detector arrangements
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1998)
The Monte Carlo program has been developed which generates the spectral responses of gamma-ray spectrometers (NaI, Ge, etc.) for radiations of arbitrarily complex composition and for easily definable disposition of sources, ...
Control and characterization of intramolecular dynamics with chirped femtosecond three-pulse four-wave mixing
(Journal of Physical Chemistry. Part A: Molecules, Spectroscopy, Kinetics, Environment and General Theory, 1999)
Experimental control and characterization of intramolecular dynamics are demonstrated with chirped femtosecond three-pulse four-wave mixing (FWM). The two-dimensional (spectrally dispersed and time-resolved) three-pulse ...
Preset count moving average digital algorithm with faster response to an increasing count rate
(Review of Scientific Instruments, 1999)
The preset count unweighted moving average (MA) algorithm for digital rate meters has been analyzed and compared to the preset count weighted MA algorithm. The correction factor applicable to the unweighted MA algorithm ...
Simple method to reduce the dead time of multichannel analyzers
(Review of Scientific Instruments, 1999)
A method to reduce the dead time of multichannel analyzers which uses multiple sample-and-hold circuits in the input circuitry of the analyzers analog-digital converter is proposed. Due to the exponential distribution of ...
A way to define the phase distribution for a single mode quantum field
(Journal of Physics. A: Mathematical and General, 1999)
The idea that the phase of single-mode field may be correctly defined as a phase difference between the state considered and a highly excited coherent state treated as the reference phase state, although present in discussions ...
The ball milling induced transformation of alpha-Fe2O3 powder in air and oxygen atmosphere
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 1999)
The mechanochemical treatment of alpha-Fe2O3 powder was done concurrently in air and oxygen atmospheres using a conventional planetary ball mill. The influence of the duration of milling and of the balls-to-powder mass ...
Soliton-induced modification of the speed of sound in quasi-one-dimensional molecular crystals
(Journal of Physics: Condensed Matter, 1998)
The influence of the anharmonic vibron-phonon coupling, arising on account of a dressing effect, on the characteristics of the lattice subsystem in quasi-one-dimensional molecular crystals was examined within the pseudo-harmonic ...
Room-temperature luminescence of AgBr quantum dots
(Chemical Physics Letters, 1999)
A new method for the preparation of 25 Angstrom AgBr quantum dots has been developed. The room-temperature emission of size-restricted AgBr crystallites was observed. The emission spectrum of 25 Angstrom AgBr quantum dots ...
Some optical properties of the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1999)
This paper compares some optical properties of different spiral inflectors using the program CASINO. The electric field distribution in the inflectors has been numerically calculated from an electric potential map produced ...
