... In string theory, elementary particles are replaced by small strings of Planck size. These strings can vibrate in different ways. However, since the strings are so small, we cannot see their extended character and their vibration: the different vibrational modes are interpreted as different elementa ...

spectroscopy of autoionization resonances in spectra of barium: new
... In this paper we applied a new relativistic approach [11-15] to relativistic studying the autoionization characteristics of the barium atom. Let us note that new approach in optics and spectroscopy of heavy atomic systems is the combined the generalized energy approach and the gauge-invariant QED ma ...
