We have calculated energies of the first two excited states of 19Mg by using a model that was previously successful for the ground state. Computed excitation energies are 1.12 and 1.54 MeV for (3/2−) and (5/2−), respectively—somewhat in disagreement with values of 1.38 and 2.14 MeV from a recent experiment.

Submitted for the MAR10 Meeting of The American Physical Society Charge-transfer excited states using a constrained density functional method1 MARCO OLGUIN, RAJENDRA ZOPE, TUNNA BARUAH, University of Texas at El Paso — Growing interest in characterizing charge-transfer (CT) processes inherent in many chemical interactions, such as metal surfaceadsorbate catalysis or light harvesting processes, ...

Excited state relaxation in zinc sulfide (ZnS) nanoparticles is studied as a model for the fate of the excited state in inorganic nanoparticles in general. A series of time-dependent density functional theory optimisations on the S1 and T1 excited states predict the existence of not merely isolated minima, as found before, but rather a connected cascade of excited state minima ending up in a co...

This letter presents a study of prospects of searching for excited leptons during Run II of the Fermilab Tevatron. We concentrate on single and pair production of excited electrons in the photonic decay channel in one CDF/DØ detector equivalent for 2 fb −1. By the end of Run IIa, the limits should be easily extended beyond those set by LEP and HERA for excited leptons with mass above about 190 ...

Water excites intense controversy among researchers. Its crucial role in the natural and biological world is unquestioned but much of the agreement stops [1] when it comes to details. In particular, how water behaves at interfaces is a central mystery. Some interfaces are hydrophobic [2], but here we are interested in polar surfaces, which attract water. This situation is common in the natural ...

We give a complete and rigorous proof of the Unruh effect, in the following form. We show that the state of a two-level system, uniformly accelerated with proper acceleration a, and coupled to a scalar bose field initially in the Minkowski vacuum state will converge, asymptotically in the detector’s proper time, to the Gibbs state at inverse temperature β = 2π a . The result also holds if the f...

The double beta decay of 100Mo to the 01 and 2 + 1 excited states of 100Ru is studied using the NEMO 3 data. After the analysis of 8024 h of data the half-life for the two-neutrino double beta decay of 100Mo to the excited 01 state is measured to be T (2ν) 1/2 = [5.7 +1.3 −0.9(stat)±0.8(syst)]·10 y. The signal-to-background ratio is equal to 3. Information about energy and angular distributions...
