Spectroscopic ellipsometry using the grating division-of-amplitude photopolarimeter (G-DOAP)

Thin Solid Films, 2004
Abstract Spectroscopic ellipsometric (SE) measurements obtained using the grating division-of-amplitude photopolarimeter (G-DOAP) are presented. G-DOAP measures all four Stokes parameters of arbitrarily polarized light over the full spectrum (550–940 nm in the present case), with no moving parts or modulators in less than 1 s.

Alpha -particle spectroscopic amplitudes for excited states of 1p-shell nuclei

Journal of Physics G: Nuclear Physics, 1986
Alpha -particle spectroscopic amplitudes were calculated for the excited normal parity states of 1p-shell nuclei. The wavefunctions of the nuclear states were approximated by the intermediate-coupling model wavefunctions. These spectroscopic amplitudes are required for studying the multistep direct sequential transfer processes.

Spectroscopic exhibitions of large-amplitude motions in halogen-containing coordination systems

SPIE Proceedings, 2000
The spectroscopic exhibitions of the structural non-rigidity effects in the series of the complex molecular systems with a few large amplitude motions are investigated with the application of the combination of original experimental and theoretical approaches which were tested by us earlier for the study of the floppy molecules.

The Distributions of Periods and Amplitudes of Late-Type Spectroscopic Binaries

1985
Photoelectric radial-velocity measurements, made on an unhurried observing schedule, have permitted the discovery of groups of spectroscopic binaries in which the usual observational discrimination against long periods and small amplitudes is much reduced.

Empirical determination of intermediate-coupling amplitudes and transition rates from spectroscopic data

Physical Review A, 1991
A simple general method is presented whereby measured spectroscopic energy-level data can be used to empirically construct the eigenvectors of intermediate coupling for an arbitrary configuration. These empirical eigenvectors can be used to elucidate the transition rates into, out of, and among the levels of the configuration by separating the effects ...

Analysis of the α-spectroscopic amplitudes of¹⁶O

Journal of Physics G: Nuclear Physics, 1978
The alpha -spectroscopic amplitudes of 16O are analysed in detail using the recent calculation of Apagyi and Fai (1976) based on the shell-model results of Zuker et al (1968). The importance of the knowledge of the precise magnitude and phase of the amplitudes is emphasised.

One-nucleon spectroscopic amplitudes for excited states of 1p-shell nuclei

Journal of Physics G: Nuclear Physics, 1987
Spectroscopic amplitudes are calculated for one-nucleon transfers between low-lying, normal parity states of 1p-shell nuclei. Calculations are performed with the intermediate-coupling model wavefunctions generated using the interaction parameters of Cohen and Kurath (1970).

Spectroscopic amplitudes for two-cluster transfer between 1p-shell nuclei

Journal of Physics G: Nuclear and Particle Physics, 1991
Spectroscopic amplitudes for separation of two clusters from 1p-shell nuclei were calculated. The calculations were performed with the aid of intermediate-coupling shell model wavefunctions. The population of final states produced by simultaneous transfer of two clusters from 1p-shell nuclei was discussed.

Large amplitude motions in coumaran: a spectroscopic and theoretical study

2004
$^{a}$E. Bondoc, T. Klots, J. Laane, J. Phys. Chem A 104, 275 (2000) ; Author Institution: Dipartimento di Chimica ``G. Ciamician'', Universit\`{a} di Bologna ; The structure of coumaran (2,3-dihydrobenzofuran) is characterized by a non-planar skeleton, due to the position of the most far apart carbon in the dihydrofuran ring. We have measured 133 a, b
