چکیده
We present here cross section results for ionization of hydrogen atoms by electron impact at 1eV, 0.5eV and 0.3eV energy above threshold, calculated in hyperspher-ical partial wave theory. The results are in excellent agreement with the available semiclassical results of Crothers et al [ 2002 ] for these energies. Considering its success above 1eV energy [ Das et al (2003) ] for various kinematic conditions, and considering the present success some advantages of the hyperspherical partial wave theory over other sophisticated theories, requiring large scale computations, are clearly demonstrated.

Mechanisms of photo double ionization of helium by 530 eV photons.
We have measured fully differential cross sections for photo double ionization of helium 450 eV above the threshold. We have found an extremely asymmetric energy sharing between the photoelectrons and an angular asymmetry parameter beta approximately 2 and beta approximately 0 for the fast and slow electrons, respectively. The electron angular distributions show a dominance of the shakeoff for ...
متن کاملHighest Energy Cosmic Rays
It is proposed that the highest energy ∼ 10 20 eV cosmic ray primaries are protons, decay products of a long-lived progenitor whose high kinetic energy arises from decay of a distant (cosmological) superheavy particle, G. Such a scenario can occur in e.g. SU (15) grand unification and in some preon models, but is more generic; if true, these unusual cosmic rays provide a window into new physics...

The quark mass function in QCD is revisited, using a gluon propa-gator in the form 1/(k 2 + m 2 g) plus 2µ 2 /(k 2 + m 2 g) −2 , where the second term gives linear confinement for m g = 0 in the instantaneous limit, µ being another scale (to be determined). To that end we propose a new (differential) form of the Dyson-Schwinger Equation (DSE) for the mass function Σ(p), based on subtractive Ren...
متن کاملElectron-impact ionization of atomic hydrogen at 2 eV above threshold
The convergent close-coupling method is applied to the calculation of fully differential cross sections for ionization of atomic hydrogen by 15.6 eV electrons. We find that even at this low energy the method is able to yield predictive results with small uncertainty. As a consequence, we suspect that the experimental normalization at this energy is approximately a factor of two too high. PACS n...
متن کامل(e,3e) on helium at low impact energy: the strongly correlated three-electron continuum.
Double ionization of the helium atom by slow electron impact (E(0)=106 eV) is studied in a kinematically complete experiment. Because of a low excess energy E(exc)=27 eV above the double ionization threshold, a strongly correlated three-electron continuum is realized. This is demonstrated by measuring and calculating the fully differential cross sections for equal energy sharing of the final-st...
