The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting
(HFS) in muonic hydrogen ($\mu $ p) with 1 ppm accuracy by means of pulsed laser …

Scattering by particles significantly smaller than the wavelength is an important physical
process in the icy and rocky bodies in our Solar System and beyond. A number of …

We present a theoretical study of two-color ionization of hydrogen with keV photons at
intensities ranging from 10 16 to 10 18 W/cm 2. We consider the atom in interaction with a …

We study the absorption and dispersion properties of a weak tunable probe field in a four-
level Y-type atomic system driven by two strong laser (coupling) fields within the framework …

A theoretical analysis is presented for the elastic Rayleigh scattering of x-rays by many-
electron atoms and ions. Special emphasis is placed on the angular distribution and linear …

The ground state energy, some low-lying excited state energies and oscillator strengths for a
hydrogen atom confined in both a Debye screening potential and finite impenetrable …

We report on the first elastic hard x-ray scattering experiment where the linear polarization
characteristics of both the incident and the scattered radiation were observed. Rayleigh …

The dynamics of a hydrogen atom confined in an impenetrable spherical box and under the
effect of Debye screening, in the presence of intense short laser pulses of few femtosecond …

The (elastic) Rayleigh scattering of hard x rays by hydrogenlike ions has been investigated
within the framework of second-order perturbation theory and Dirac's relativistic equation …

In this paper, we extend to three-photon radiative transitions in hydrogenic ions our fully
relativistic multipole approach [Z. Bona, Phys. Rev. A 89, 022514 (2014) 1050-2947 …
