Unitary correlation in nuclear reaction theory

open access: yes, 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 ...

The Status of Spectroscopic Data for the Exoplanet Characterisation Missions [PDF]

open access: yes, 2014
The status of laboratory spectroscopic data for exoplanet characterisation missions such as EChO is reviewed. For many molecules (eg H2O, CO, CO2, H3+, O2, O3) the data are already available.

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

open access: yesResults 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.

Optical Spectroscopy of Distant Red Galaxies

open access: yes, 2009
We present optical spectroscopic follow-up of a sample of Distant Red Galaxies (DRGs) with K 2.3, in the Hubble Deep Field South, the MS 1054-03 field, and the Chandra Deep Field South. Spectroscopic redshifts were obtained for 15 DRGs. Only 2 out of 15

The IACOB project. VI. On the elusive detection of massive O-type stars close to the ZAMS

open access: yes, 2020
The apparent lack of massive O-type stars near the zero-age main sequence (at ages < 2 Myr) is a topic widely discussed. Different explanations for this elusive detection have been proposed, but no firm conclusions have been reached yet. We reassess this

Threshold Effects in Multi-channel Coupling and Spectroscopic Factors in Exotic Nuclei [PDF]

open access: yes, 2007
In the threshold region, the cross section and the associated overlap integral obey the Wigner threshold law that results in the Wigner-cusp phenomenon. Due to flux conservation, a cusp anomaly in one channel manifests itself in other open channels, even

Synthesis, spectral and thermo-kinetics explorations of Schiff-base derived metal complexes

open access: yesOpen Chemistry, 2020
Schiff-base ligand, 2,6-bis(benzimino)-4-phenyl-1,3,5-triazine (L), and its transition metal complexes of Co(ii), Ni(ii), and Cu(ii) were synthesized by refluxing the reaction mixture and its analytical, spectral, and thermogravimetric characteristics ...
