We report in the present paper accurate computed resonant parameters for the doubly excited 1 S e states of the He-like Li+ ion lying below the N = 2 and N = 3 Li 2 + ( N l ) hydrogenic thresholds. Our theoretical method is based on the diagonalizati

We report in this paper computed values of the energy positions and widths of the lowest 1^P^o singlet doubly excited states of the helium atom. The results are obtained by a direct numerical solution of the time-independent Schrodinger equation usin

We numerically investigate the removal of the two outer electrons in the X = He, Li + , C 4 + , Be, B + and Ne 6 + targets by the absorption of a single photon of energy in the extreme UV/soft X-ray spectral region. Our theoretical method to describe

The two-photon double ionization process along the He isoelectronic sequence (He − Ne8+) is investigated by solving the full-dimensional time-dependent Schrodinger equation in an intense laser field. The ionization is triggered from the ground stat

We report in this paper computed resonant parameters for the lowest singlet doubly excited 1Po states of the Li+ ion lying below the N = 2 and N = 3 hydrogenic thresholds. In our previous works (see Barmaki et al., 2014 and references therein), the c

We investigate the two-photon double ionization of a beryllium atom by intense ultrashort laser pulses. We apply a nonperturbative approach to solve the time-dependent Schrödinger equation. We treat the atom as a two-active-electron system with two

We theoretically investigate the doubly excited 1Po resonance series of the O6+ ion converging towards the N = 3 threshold. No experimental measurements of the energy positions E and the widths Γ for the states belonging to the different series have

We present in this paper an investigation of the nonlinear process of above-threshold ionization. The process arises when an atomic or molecular system, exposed to an intense laser pulse, continues to absorb more photons than that needed for the ioni

We numerically investigate the ionization mechanism in a real hydrogen atom under intense fem to second chirped laser pulses. The central carrier frequency of the pulses is chosen to be 6.2 eV (λ = 200 nm), which corresponds to the fourth-harmonic o
