The electric quadrupole, hexadecapole moments, energy (kJmol -1) for some armchair polyhex carbon nanotubes TUVC6[2p,q] are performed by Beck-Lee-Yang-Parr [B3LYP] on 3-21G basis set using the standard procedure indices GAUSSIAN 98, then the Padmakar-Ivan (PI) index of TUVC6[2p,q] nanotubes in the terms of their circumference (2p) and lengh (q) is calculated and the relationships between the Pa...

This paper provides an extension of previous work [l] on the pionic 2p-1s yields for nuclei flom N to Na in two directions. We report here on measurements of the 2p-1s yields for the lighter nuclei Be, FOB, natB and C, and from these data we deduce the natural 2p level widths r(2p) due to pion absorption by comparison with the 2p-1s X-ray transition rate WX. In ref. 1, WX was calculated on a pu...

Observation of infrared electronic transitions involving the 1 (1)Deltag state of 7Li2 has instigated an investigation of Born-Oppenheimer breakdown in four singlet electronic states correlating with (2s+2s), (2s+2p), and (2p+2p) lithium atoms. The 1 (1)Deltag state, which correlates at long range with (2p+2p) atoms, has been observed in emission from the (5p) (1)Piu Rydberg state and in 1 (1)D...

Simulations of solid-state Si N M R spectra in nitrogen-containing silicon ceramics and glasses are described. The range of SiN ; t04 ._x tetrahedra is covered, with emphasis on the experimental conditions needed to observe the effect of the incompletely averaged Si, 1 4 N dipolar coupling. A simple equation is discussed concerning its use in the interpretation of these Si spectra, including th...

The ionic liquid 1,3-dimethyl-imidazolium-dimethylphosphate ([MMIM]+[DMP]−) was analyzed using (hard) x-ray photoelectron spectroscopy. Here, XPS and HAXPES spectra are shown in comparison. For the acquisition of spectra, monochromatic Al Kα radiation at 1486.6 eV used, while for Cr 5414.8 applied. survey scans high-resolution P 2p, 2s, C 1s, O N 1s both methods KL2,3L2,3, KL1L2,3 shown.

We illustrate a theoretical condition under which a two-body decay of a resonance violates time reversal invariance. Moreover, we examine some cases for which this condition looks particularly simple. As a consequence, we deduce tests of time reversal violation for weak decays involving spinning particles.

The 2p-3d core-hole interaction in the L2.3 absorption spectra of the transition metals is treated within time-dependent density functional theory. A simple three-level model explains the origin of the strong deviations from the one-particle branching ratio and yields matrix elements of the unknown exchange-correlation kernel directly from experiment.

A high-flux beam of mass-filtered F+ at low energy (100-1300 eV) was scattered off Al and Si surfaces to study core-level excitations of F0 and F+. Elastic scattering behavior for F+ was observed at energies <300 (500) eV off Al (Si) for a 90 degrees lab angle. However, above this energy threshold, orbital mixing in the hard collision step results in electronic excitation of F via molecular orb...
