"Systematic comparison of positron- and electron-impact excitation of the nu(3) vibrational mode of CF4" Phys. Rev. A 72 (2005), 062702. J. P. Marler and C.M. Surko (PDF)
... The vibrational excitation of CF4 by positron impact, reported in Ref. 关3兴, was done by making minor modifications to an existing three-stage buffer gas trap. Positrons were trapped and cooled in the three-stage trap using an N2 buffer gas. The N2 was then pumped out, and CF4 was introduced into the ...

The resonant values were not used because the singularities introduce infinite values into the calculations which is problematic in order to make the numerical process converge. A small ab ...

The Scattering of α and β Particles by Matter and
... with atoms of matter. This scattering is far more marked for the β than for the α particle on account of the much smaller momentum and energy of the former particle. There seems to be no doubt that such swiftly moving particles pass through the atoms in their path, and that the deflexions observed a ...

... charges. The point form of Ohm's law does not hold. In rarefied gases the paths of accelerated ions between two successive collisions are relatively long, so that they can acquire a considerable kinetic energy. As a consequence, various new effects can be produced. The best known is probably a chain ...
