Unitary correlation in nuclear reaction theory

, 2010
We prove that the amplitudes for the (d,p), (d,pn) and (e,e'p) reactions determining the asymptotic behavior of the exact scattering wave functions in the corresponding channels are invariant under unitary correlation operators while the spectroscopic ...

Accurate fundamental parameters for 23 bright solar-type stars [PDF]

, 2010
We combine results from interferometry, asteroseismology and spectroscopy to determine accurate fundamental parameters of 23 bright solar-type stars, from spectral type F5 to K2 and luminosity classes III to V. For some stars we can use direct techniques

Study on the distribution characteristics of α-Solanine in different parts of Solanum nigrum based on infrared spectroscopy

Results in Chemistry
This study employs Fourier Transform Infrared Spectroscopy (FTIR) to quantitatively analyze the distribution patterns and metabolic roles of α-solanine across different organs (roots, stems, leaves, flowers, and fruits) of Solanum nigrum.

Spectroscopic Portraiture

Annals of Science, 2002
This paper describes a now widely forgotten tradition in the nineteenth century which-to borrow a simile used or implied by the actors themselves-may be described as 'spectroscopic portraiture'.(1) Quite unlike the later obsession with numerical precision in wavelength measurement, and also in stark contrast to the contemporary vogue of photographic ...

Five More Massive Binaries in the Cygnus OB2 Association

, 2009
We present the orbital solutions for four OB spectroscopic binaries, MT145, GSC 03161-00815, 2MASS J20294666+4105083, and Schulte 73, and the partial orbital solution to the B spectroscopic binary, MT372, as part of an ongoing study to determine the ...

A Statistical Study of the Si IV Resonance Line Parameters in 19 Be Stars

Open Astronomy, 2011
Using the GR model, we analyze the ultraviolet Si IV resonance lines in the spectra of 19 Be stars of different spectral subtypes, in order to detect the presence of absorption components and to analyze their characteristics.
