Mean values of local operators in highly excited Bethe states

Highly polarizable singlet excited States of alkenes.

Effective local potentials for excited states.

The constrained variational Hartree-Fock method for excited states of the same symmetry as the ground state [Chem. Phys. Lett. 287, 189 (1998)] is combined with the effective local potential (ELP) method [J. Chem. Phys. 125, 081104 (2006)] to generate Kohn-Sham-type exact-exchange potentials for singly excited states of many-electron systems. Illustrative examples include the three lowest (2)S ...

Radiative lifetimes of highly excited states in rubidium

2014 Measurements have been made of the natural radiative lifetimes of highly excited rubidium (9 ~ n ~ 18) S and D states. These results, as well as those already published concerning P and F states, agree well with the theoretical lifetimes calculated by the Bates-Damgaard method. J. Physique 41 (1980) 119-121 1 FTVRIER 1980, Classification Physics Abstracts 32.70 In the past few years, measu...

Excited mesons in a Bethe-Salpeter approach

In theoretical hadron physics mesons are a center of attention. Constructed in a simpler way than baryons in the quark model, they still present a considerable challenge if one aims at an understanding of all their aspects in terms of quarks and gluons in the context of Quantum Chromodynamics, the quantum field theory of the strong interaction. Complementary to (constituent-) quark models, redu...

Mixing between Vibrationally Highly Excited Resonance States of DCO

Over the last years, state-resolved studies of unimolecular reactions of small and intermediate size molecules have provided considerable new insight into the dissociative dynamics of vibrationally highly excited molecules. In our laboratory, we use the technique of stimulated emission pumping (SEP) for preparing and probing selected highly excited states. In a case study of DCO ( X~ A’), we de...
