Atomic physics and the basic concepts of quantum theory have been probed in the last fifty years by using the techniques of optics and lasers in the visible range. The new powerful accelerators, storage rings, and various large scale devices, such as ion beams, synchrotron radiation, plasma confinement machines, powerful lasers, etc. developed by the nuclear physicists and high technology engineers have allowed, in the past three decades, new, unexpected and more general insights of atomic structure and more accurate checks of quantum mechanics. It is now possible to prepare any kind of atom or ion, having any number of electrons in any quantum states (atomic manipulations), and to trap or set them in defined places on surfaces. The study of these atomic species having electrons in any deep, or highly excited levels requires the use of electromagnetic transitions in a much wider range of wavelengths than in optics, and, because most of the time they are in autoionizing states, of Auger spectrometry. It is the purpose of this talk to review some of the most salient discoveries in the field since this time, to present some of the most recent and exciting results obtained in the last decade, and future prospects. © 2000 American Institute of Physics.

    The inner-shell photo-ionization (ISPI) scheme requires photon energies at least high enough to photo-ionize the K-shell, ∼286 eV, in the case of carbon. As a consequence of the higher cross-section, the inner-shell are "selectively" knocked out, leaving a hole state 1s2s[SUP2]2p[SUP2] in...

    Based on 'length and energy scale matching' theory, we put forward a model for the Ar17+ ion in grazing incidence on an Al surface. Using the model and a more detailed side feeding rate, the inner-shell filling and X-ray emission of the incident Ar17+ ion are minutely studied. The results show...

    The study of inner-shell transitions induced by an intense (>1019 W/cm²) ultrashort (~5 fs) x-ray pulse provides a challenging opportunity to investigate the behavior and dynamics of hollow atoms and to explore the feasibility of creating population inversions in some of the inner-shell...

    The femtosecond population dynamics of gold irradiated by a coherent high-intensity (>1017 W/cm²) x-ray laser pulse is investigated theoretically. There are two aspects to the assembled model. One is the construction of a detailed model of platinum-like gold inclusive of all inner-shell...

    Weakly interacting massive particles (WIMPs) are shown to be studied by measuring X-rays following inner-shell ionizations associated with WIMP nuclear interactions. Inner-shell electrons are well ionized by WIMP nuclear interactions. K shell ionization probabilities are of the order of 0.20...

    The absolute laser conversion efficiency to Kα-like inner shell x-rays (integrated from Kα to Kβ) is observed to be an order of magnitude higher in argon gas jets than in solid targets due to enhanced emission from higher ionization stages following ultrashort pulse laser irradiation....

    Implosions of brass wire arrays on Zebra have produced L-shell radiation as well as inner-shell Kα and Kβ transitions. The L-shell radiation comes from ionization stages around the Ne-like charge state that is largely populated by a thermal electron energy distribution function, while the...
