“…A number of works are devoted to the probability considerations of cross sections for photo processes in the field of USP [10][11][12][13][14]. Also USP scattering on different targets plays an important role (apart from the fundamental importance) because it may be used as a new tool for the investigation of various objects including nanoparticles [14], solid-state, complex molecules. Also bio-medical applications have been proposed [15].…”

The inclusion of the retardation term, non-dipole interaction and an efficient scattering tensor approximation allowed studying the scattering probability in dependence of the pulse duration for different carrier frequencies. Numerical calculations carried out for Mg, Al and Fe atoms demonstrate that the scattering probability is a highly non-linear function of the pulse duration and has extrema for pulse carrier frequencies in the vicinity of the resonance-like features of the polarization charge spectrum. Closed expressions for the nondipole correction and the angular dependence of the scattered radiation are obtained.

“…Calculations USP interaction with various atomic systems and the detection of specific laws inherent in this interaction was conducted in several studies. So, photoionization of noble gas atoms under the action of USP of different shapes was considered in the works [5,6]. In the work [6] it was shown in particular that the dependence of the photoionization probability on the USP duration essentially depends on spectral features of the process cross-section.…”

“…So, photoionization of noble gas atoms under the action of USP of different shapes was considered in the works [5,6]. In the work [6] it was shown in particular that the dependence of the photoionization probability on the USP duration essentially depends on spectral features of the process cross-section. For example, in case of a xenon atom, the cross-section of photoionization of which has a giant resonance, the ionization probability as a function of the USP duration has a maximum in the attosecond range for specific carrier frequencies of a pulse.…”

Excitation of highly charged ions in plasmas under the action of ultrashort electromagnetic pulses is investigated theoretically in the frame of perturbation theory. The study is based on analytical expression for probability of bound-bound transition which is derived for Gaussian pulse and Doppler broadening of spectral line shape of the transition. Electronic transitions from the ground state of hydrogen-like ions are considered with account for fine splitting of upper energy levels. The main attention is paid to the dependence of the excitation probability on pulse duration for various ion charges and carrier frequencies of the pulse. The results obtained are of interest for plasma diagnostics based on ion excitation from ground state by ultrashort pulses.
