It is shown that, for any spatial frame L (i.e., L is a complete lattice generated by the set of all prime elements), both the specialization L-preorder of L-topological spaces introduced by Lai and Zhang [Fuzzy preorder and fuzzy topology, Fuzzy Sets and Systems 157 (2006) 1865–1885] and that of L-fuzzifying topological spaces introduced by Fang and Qiu [Fuzzy orders and fuzzifying topologies,...

The interference pattern of the resonance fluorescence from a J = 1/2 to J = 1/2 transition of two identical atoms confined in a three-dimensional harmonic potential is calculated. Thermal motion of the atoms is included. Agreement is obtained with experiments [Eichmann et al., Phys. Rev. Lett. 70, 2359 (1993)]. Contrary to some theoretical predictions, but in agreement with the present calcula...

We report IR active N2 stretching frequencies in isolated and size selected cobalt cluster nitrogen adsorbate complexes, [Con(N2)1](+) as recorded by virtue of InfraRed Photon Dissociation (IRPD) spectroscopy. The observed frequencies of the [Con(N2)1](+) complexes (n = 8-17) are significantly redshifted (2180 to 2290 cm(-1)) with respect to the IR inactive vibrations of free N2 (2359 cm(-1)). ...

We present detailed analyses of the absorption spectrum seen in QSO 2359– 1241 (NVSS J235953−124148). Keck HIRES data reveal absorption from twenty transitions arising from: He i, Mg i, Mg ii, Ca ii, and Fe ii. HST data show broad absorption lines (BALs) from Al iii λ1857, C iv λ1549, Si iv λ1397, and Nv λ1240. Absorption from excited Fe ii states constrains the temperature of the absorber to 2...
