Cross-sections for neutral atoms and molecules collisions with charged spherical nanoparticle

Cross Sections for Electron Collisions with Water Molecules

Cross section data have been compiled from the literature ~to the end of 2003! for electron collisions with water (H2O! molecules. All major collision processes are reviewed including: total scattering, elastic scattering, momentum transfer, excitation of rotational, vibrational, and electronic states, ionization, electron attachment, dissociation, and emission of radiation. In each case we ass...

Measurement of Neutral and Charged Current Cross Sections in Electron-Proton Collisions at High H1 Collaboration

The inclusive single and double differential cross sections for neutral and charged current processes are measured with the H1 detector at HERA, in the range of four-momentum transfer squared between and GeV , and Bjorken between and . The data were taken in 1998 and 1999 with a centre-of-mass energy of 320 GeV and correspond to an integrated luminosity of 16.4 . The data are compared with rece...

HIGH Q2 NEUTRAL AND CHARGED CURRENT CROSS SECTIONS IN e+p COLLISIONS AT HERA

The ZEUS experiment at HERA has collected 46:6pb ?1 of e + p data during 1994 to 1997. This amount is more than twice that of data used in our previous analysis reporting an excess of high Q 2 and high x neutral current(NC) events. We have measured Born level cross sections as a function of Q 2 both for neutral and charged current(CC) deep inelastic scattering reactions using all data up to 199...

Cross Sections for the Collisions of Alkaline Earth Atoms

The total attenuation cross sections, a*, were measured for collisions of an excited atomic beam of Mg, Ca or Sr with a target of Cl2 molecules. The experimental o* values equal: 85 Ä2, 100 Ä2 and 180 Ä2 for Mg*, Ca* and Sr*, respectively. Moreover, the reactive cross sections, OR were calculated, assuming the "harpoon mechanism" for the reactions in question. The obtained values are: OR* (Mg* ...
