Publikováno v: Physical Review A. 10:745-748
The foil-excitation method has been used to study the extreme ultraviolet spectra of highly ionized oxygen and fluorine. Several previously unreported lines in heliumlike fluorine are reported and other newly reported lines in heliumlike oxygen have

Convoy electrons from solids in coincidence with emergent projectile charge state
Autor: R. Laubert, S. B. Elston, Sven Huldt, M. Breinig, R.S. Thoe, L. Liljeby, Ivan A. Sellin
Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 14:859-862
Following the passage of fast ions through thin solid targets, the velocity distribution of forward ejected continuum electrons, centred at a velocity about that of the projectile, is found to be substantially independent of the emergent projectile c

Charge dependence ofKx-ray production in nearly symmetric collisions of highly ionized S and Cl ions in gases
Autor: Matt D. Brown, R. Laubert, J. R. MacDonald, L. M. Winters, Ivan A. Sellin, Stephen J. Czuchlewski, J. R. Mowat
Publikováno v: Physical Review A. 14:1997-2009
Using gas targets, $K$ x-ray cross sections have been measured as a function of projectile charge state in nearly symmetric collisions for highly ionized S and Cl ions at a velocity comparable to that of the $K$-shell electrons. For bare nuclei, the

Strong Isotope Dependence ofK-Vacancy Production in SlowNe+-Ne Collisions
Autor: I. A. Sellin, F. K. Chen, C. A. Peterson, R. S. Peterson, S. B. Elston, R. Laubert
Publikováno v: Physical Review Letters. 37:984-987
Large isotope effects in the K x-ray yields from collisions of /sub A/Ne/sup +/-/sub B/Ne(A,B=20,22) have been observed. For slow collisions (relative velocities approx.1/3 a.u.) the K x-ray yields do not scale well with either relative velocity or c

Yield of convoy electrons from solids

Publikováno v: Nuclear Instruments and Methods. 170:557-560
The number of convoy electrons emitted in the forward direction from solid targets of C, Al, Ag. and Au per incident 1–4 MeV/amu H, O, Si, and Ni projectile is reported. As expected, the yield is independent of target thickness and of the incident

Experiments concerning electron capture and loss to the continuum and convoy electron production by highly ionized projectiles in the 0.7 - 8.5-MeV/u range transversing the rare gases, polycrystalline solids, and axial channels in gold

Velocity spectra of electrons emitted into the forward direction have been measured for 0.7--8.5-MeV/u projectile ions traversing He, Ne, and Ar targets, polycrystalline solids (C, Al, Ag, Au), and axial channels in gold. Spectral shapes and yields a
