Signatures of direct double ionization under XUV radiation
In anticipation of upcoming two-photon double ionization of atoms and particularly Helium, under strong short wavelength radiation sources (45 eV), we present quantitative signatures of direct twophoton double ejection, in the photoelectron spectrum (PES) and the peak power dependence, that can be employed in the interpretation of related data. We show that the PES provides the cleanest signatu...
متن کاملDirect two-photon double ionization of helium
The role of electron correlation, i.e. the electron-electron repulsion, in non-sequential two-photon double ionization of helium has been widely debated in literature, and the issue is not yet fully resolved. We present total cross sections for this process obtained within a one dimensional model of the helium atom. In our calculations the cross sections are obtained in two ways. Firstly, the t...
متن کاملInner-Shell Ionization and Fragmentation of Isolated Endohedral Fullerene Ions by XUV Radiation
The photon–ion merged-beams technique for photoabsorption studies of ionized nanoparticles with synchrotron radiation is introduced. As an example, recent results from photoionization and photofragmentation of the endohedral fullerene ions Lu3N@C 80, Lu3N@C 2+ 80 , and Lu3N@C 3+ 80 are briefly discussed, highlighting the sensitivity and versatility of the experimental technique.
متن کاملProbing electron correlation via attosecond xuv pulses in the two-photon double ionization of helium.
Recent experimental developments of high-intensity, short-pulse extreme ultraviolet light sources are enhancing our ability to study electron-electron correlations. We perform time-dependent calculations to investigate the so-called "sequential" regime (variant Planck's over 2piomega > 54.4 eV) in the two-photon double ionization of helium. We show that attosecond pulses allow us not only to pr...
متن کاملTime-Dependent B-Spline R-Matrix Approach to Double Ionization of Atoms by XUV Laser Pulses
We present an ab initio and non-perturbative time-dependent approach to the problem of double ionization of a general atom driven by intense XUV laser pulses. After using a highly flexible B-Spline R-matrix method to generate field-free Hamiltonian and electric dipole matrices, the initial state is propagated in time using an efficient ArnoldiLanczos scheme. Test calculations for double ionizat...
