First-Principles Study of Structure, Electronic and Optical Properties of HgSe in Zinc Blende (B3) Phase

In this paper, the structural parameters, energy bands structure, density ofstates and charge density of HgSe in the Zincblende(B3) phase have been investigated.The calculations have been performed using the Pseudopotential method in theframework of density functional theory (DFT) by Quantum Espresso package. Theresults for the electronic density of states (DOS) show tha...

Photofragmentation spectra and structures of Sr 1 Arn , n 5 2 – 8 clusters : Experiment and theory

The total photofragmentation cross sections of size selected SrArn ,n52 – 8, clusters have been recorded in a time of flight ~TOF! mass spectrometer. In the energy range of 21 000–27 000 cm three absorption bands are observed that are attributed to transitions from the ground to the three excited states that correlate to the 5p orbitals of strontium. No vibrational structure in the spectral ban...

Metallic evolution of small magnesium clusters

Structural and electronic properties of small magnesium clusters (N ≤ 13) are studied using a first-principles simulation method in conjunction with the density functional theory and generalized gradient correction approximation for the exchange-correlation energy functional. It is observed that the onset of metallization of magnesium clusters is hard to assign since both the s-p hybridization ...

153403 - Observation of Atomiclike Electronic Excitations in Pure 3 He and 4 He Clusters Studied by Fluorescence Excitation Spectroscopy

The structure of the electronically excited states of 3He and 4He clusters is investigated using fluorescence excitation spectroscopy. Distinct bands are observed energetically close to atomic 1s-ns, nd, np transitions and attributed to perturbed excited He atomiclike states with different principle and orbital quantum numbers. The line shifts and widths of the bands of 3He and 4He clusters of ...
