Fast (0.35--1.2-MeV) He[sup [minus]] ions produced by double electron capture have been observed in He[sup +]-He collisions. The thickness of the gas-jet target (4[times]10[sup 13]--10[sup 15] atoms/cm[sup 2]) has been calculated without any separate

We give upper bounds on the photoproduction in overcritical electric fields of a neutral light boson which could explain the correlated e+e- production seen at GSI-Darmstadt in heavy-ion-atom collisions.

A Monte Carlo computer program was developed to calculate the angular distribution of fragments resulting from the breakup of fast hydrogen clusters ${\mathrm{H}}_{\mathit{n}}^{+}$ when traversing thin amorphous carbon foils. The three-dimensional re

Ab initio molecular electronic-structure theory has been used in an attempt to characterize the low-lying stationary points on the potential energy hypersurface of positive ionic hydrogen clusters. Using triple-zeta-plus-polarization basis sets, self

We have measured the Lyman-\ensuremath{\alpha} radiation following foil breakup of hydrogen ionic clusters ${\mathrm{H}}_{\mathit{n}}^{+}$ (n=2 and n=3 to 61, odd) with velocities above and around the Bohr velocity. An enhancement of this radiation w

We describe a search for a light neutral object X0 possibly produced by ≈ 100 GeV photons interacting with the QED strong field encountered along the axis of a cooled Ge crystal. We look at the e+e− decay mode, in short (10−18−10−12 s) as w

Angular and energy distributions of electrons and positrons created by 83–133 GeV photons in an aligned crystal (strong field pair creation) have been measured. The experiment exhibits the “blocking” effect for the positron and the difference o

The total secondary-electron yield from thin carbon foils traversed by heavy ions has been measured as a function of the projectile atomic number ${\mathit{Z}}_{\mathit{p}}$, the initial charge state, and the incident velocity. For nearly all project

Radiative decays of excited He+ (4→3) ions emerging from thin carbon foils have been observed for a range of 25–600 keV/u projectile velocities in charge exchange equilibrium and non-equilibrium situations, respectively. A picture involving vario

The interaction of moving ions with single crystals is very sensitive to the orientation of the incident beam with respect to the crystalline directions of the target. Our experiments show that high energy heavy ion channeling deeply modifies their s
