چکیده

The optical response of the lowest energy isomers of the C20 family is calculated using time-dependent density functional theory within a real-space, real-time scheme. Significant differences are found among the spectra of the different isomers, and thus we propose optical spectroscopy as a tool for experimental investigation of the structure of these important clusters.

X iv : n uc l - ex / 0 41 00 36 v 1 2 5 O ct 2 00 4 1 Branching ratio measurements of the 7 . 12 - MeV state in 16

Knowledge of the γ-ray branching ratios of the 7.12-MeV state of 16 O is important for the extrapolation of the 12 C(α,γ) 16 O cross section to astrophysical energies. Ground state transitions provide most of the 12 C(α,γ) 16 O total cross section while cascade transitions have contributions of the order of 10-20%. Determining the 7.12 → 6.92-MeV branching ratio will also result in a better ext...

Solid State Process for Preparation of Nickel Oxide Nanoparticles: Characterization and Optical Study

In the present work, we report preparation of NiO nanoparticles with well-defined plate morphology by solid-state reaction of NiCl2∙6H2O and the Schiff base ligand N,N′-bis-(3-methoxysalicylidene)benzene-1,4-diamine), as a novel precursor via solid state thermal decomposition method. This method is a simple and environmentally friendly for preparing t...

X-ray Absorption Spectroscopy Study of the Effect of Rh doping in Sr2IrO4

We investigate the effect of Rh doping in Sr2IrO4 using X-ray absorption spectroscopy (XAS). We observed appearance of new electron-addition states with increasing Rh concentration (x in Sr2Ir1-xRhxO4) in accordance with the concept of hole doping. The intensity of the hole-induced state is however weak, suggesting weakness of charge transfer (CT) effect and Mott insulating ground states. Also,...

Direct Correlation of Charge Transfer Absorption with Molecular Donor:Acceptor Interfacial Area via Photothermal Deflection Spectroscopy.

Here we show that the charge transfer (CT) absorption signal in bulk-heterojunction solar cell blends, measured by photothermal deflection spectroscopy, is directly proportional to the density of molecular donor:acceptor interfaces. Since the optical transitions from the ground state to the interfacial CT state are weakly allowed at photon energies below the optical gap of both the donor and ac...

We report photoassociative spectroscopy of 88Sr2 in a magneto-optical trap operating on the 1S0 → 3P1 intercombination line at 689 nm. Photoassociative transitions are driven with a laser red-detuned by 600-2400MHz from the 1S0 → 1P1 atomic resonance at 461 nm. Photoassociation takes place at extremely large internuclear separation, and the photoassociative spectrum is strongly affected by rela...
