Neutral fragment products from dissociative collisions of triatomic hydrogen like ions incident on He atoms were studied. Absolute differential and total cross sections are reported here in the energy range of 1.00-5.00 ...

Measurements of the absolute total and differential cross sections for the production of protons and hydrogen atoms in the energy range of 1-5 keV for reactions of H-2(+) molecular ions in Ar and Kr targets are reported. ...

We extend the theory of diffraction in time to particles with angular momentum. We consider the problem of the sudden release of a particle which initially was inside a spherical trap. The particle's free time evolution ...

We investigated H+ and He+ fragment production from the dissociation of HeH+ ions in collision with a He target. This occurs through either the He++H or the He+H+ channel. We also investigated He2+ and H- production, which ...

It is demonstrated that for very thin or very shallow rectangular barriers the transmission amplitude possesses an antibound pole situated very close to threshold energy. The transmission coefficient and the delay time at ...

We show the equivalence of the functions G(p)(t) and \Psi(d,t)\(2) for the "passage time" in tunneling. The former, obtained within the framework of the real-time Feynman histories approach to the tunneling time problem, ...

Experimental and theoretical investigation of single-electron capture and additional experimental studies of single-electron loss cross sections in He+-Ar collisions at impact energies of 1.5-5.0 keV for experimental studies ...
