Convergent close-coupling approach to antiproton and proton collisions with atomic and molecular targets
MetadataShow full item record
A semi-classical single-centre convergent close-coupling method for describing antiproton collisions with atomic and molecular targets has been developed. Excitation and ionisation of noble-gas atoms, molecular hydrogen and water molecule by antiproton impact have been investigated. In addition, a semi-classical two-centre convergent close-coupling method has been developed to study collisions of protons with atomic hydrogen including electron capture into bound and continuum states of the projectile. Calculated cross sections are in good agreement with experimental data.

Conceptual change in secondary chemistry : the role of multiple analogical models of atoms and molecules.Harrison, Allan G. (1996)Chemistry textbooks and teachers frequently use a variety of metaphors, analogies and models to describe atomic and molecular structures and processes. While it is widely believed that multiple analogical models encourage ...
Bioslurry as a Fuel. 7: Spray Characteristics of Bio-Oil and Bioslurry via Impact and Twin-Fluid AtomizersGhezelchi, M.; Garcia-Perez, M.; Wu, Hongwei (2015)This study reports the spray characteristics of two fast pyrolysis bio-oils with different viscosities (0.0753 and 0.1522 Pa·s at 21 °C) and a set of bioslurry samples prepared from the bio-oils at various biochar loading ...
Meijer, T.; Beardmore, Joshua; Fabrie, C.; Van Lieshout, J.; Notermans, R.; Sang, R.; Vredenbregt, E.; Van Leeuwen, K. (2011)Atom lithography uses standing wave light fields as arrays of lenses to focus neutral atom beams into line patterns on a substrate. Laser cooled atom beams are commonly used, but an atom beam source with a small opening ...
