“…1; for more details, see Skobelev et al, 2012). Transitions of this kind were also observed in experiments on the interaction of the ion beams (Briand et al, 1996;Bailey et al, 1990;Limburg et al, 1995;Ninomiya et al, 1997;Winter et al, 1999;Schenkel et al, 1999;McMahon et al, 2011;Rzadkiewicz et al, 2010), synchrotron radiation (Diamant et al, 2000b;2000a;, or X-ray free electron laser beams (Vinko et al, 2012) with a solid target. The first observation of the similar emission pattern for multi-charged ions was done at the Naval Research Laboratory's NIKE KrF laser facility using ns laser pulses (Aglitsky et al, 1996).…”

The short review on the possible applications of the hollow ion spectra for the diagnostics of the high-temperature plasma created by intensive laser and particle beams is presented. Because of the hollow ion spectra features are defined mainly by the mechanisms of their excitation, we consider the various types of the high-temperature plasma where different excitation processes are important. It is shown that like ordinary spectral lines, spectra of the hollow ions offer considerable diagnostic opportunities. At the present time, hollow ion spectra are used mainly to investigate plasma heated by X-ray radiation, but the hollow ions must be generated when plasma is heated by fast heavy ion beams too. In this case, the resultant substance state will be also characterized by solid-state density, and some spatial regions of targets will have relatively low temperatures, i.e., will be a nonideal plasma. It is emphasized that hollow ion spectra are promising diagnostic tool for both nonideal plasma and warm dense matter.

“…Emission from hollow atoms have also been used as a diagnostic for studies of warm dense matter. Experimentally, the formation of hollow atoms has been achieved through neutralization of highly charged ions within solids (Briand et al, 1990(Briand et al, , 1996Gauthier et al, 1995;Aglitsky et al, 1996;Suto & Kagawa, 1998;Moribayshi et al, 2001;Rosmej et al, 2000), through collisions in cluster targets (McPherson et al, 1994a(McPherson et al, , 1999b, and even in gaseous targets . More recently, hollow atom spectra have been explored from heavy atom targets (Diamant et al, 2000a(Diamant et al, , 2000b(Diamant et al, , 2001Shigeoka et al, 2004) using synchrotron radiation.…”

An investigation is made of the role of hollow atoms in the spectra of an ultrashort-pulse-laser-driven Ar cluster target. Experimental measurements are presented from an Ar cluster-gas target using short-pulse lasers with various intensities, durations, and contrasts. Calculations in support of these measurements have been performed using a detailed atomic kinetics model with the ion distributions found from solution of the time-dependent rate equations. The calculations are in good agreement with the measurements and the role of hollow atoms in the resulting complicated spectra is analyzed. It is demonstrated that, although the presence of hollow atoms is estimated to add only around 2% to the total line emission, signatures of hollow atom spectra can be identified in the calculations, which are qualitatively supported by the experimental measurements.

“…Most parts of the potential energy of the ions would be deposited on the surface [11][12][13] . The process can induce many kinds of secondary sputtering productions, such as auger-electron, proton, and cluster ions [14][15][16][17] , and X-ray emission from the projectile and target atoms [11,18] . When ions interact with the solid surface, the kinetic energy effects play a certain role in the processes of X-ray emission of the target atom, and the potential energy deposition has an influence on these processes.…”
