single-valence electron atoms are an important class of atoms. their oscillator strengths are their important properties. knowing the oscillator strengths one can easity calculate the transition probabilities of the spectral lines and hence the lifetimes of energy levels of most atoms. the oscillator strengths of the spectral lines of most atoms are not knoen with sufficient accuracy due to the...

We report experimental observation of cycle-cycle bursting near homoclinic bifurcation in a selfoscillating Chua oscillator when it is diffusively coupled to another excitable Chua oscillator. The excitable oscillator induces an asymmetry in the self-oscillating Chua oscillator via coupling. The coupling strength controls the strength of the asymmetry that plays a key role in transition to burs...

Dipole plasmon resonances are described quantum mechanically using configuration interaction (CI). A fictitious system of three interacting configurations is considered, which yields three excited states. Excited states energies and oscillator strengths are derived from the eigenvalues and eigenvectors of the CI matrix, where the diagonal elements α(i) (i = 1, 2, 3) correspond to the interactin...

Cl I is the atomic species most directly coupled to molecular hydrogen due to its chemistry. Its weakest lines are thereby probably the best tracer of optically thick H 2 components in diffuse clouds. We report on the empirical determination of the oscillator strengths for four Cl I absorption lines predicted to be weak and often detected toward moderately reddened sight lines observed with the...
