Time-dependent close-coupling calculations of positronium formation in positron-hydrogen collisions
Positronium-formation cross sections from positron-hydrogen collisions are calculated by solving a set of close-coupled, time-dependent partial differential equations. These cross sections are determined by propagating a time-evolving wave packet on a two-dimensional radial lattice and then projecting the wave function onto the stationary states of the atom. Calculations are performed through L...
متن کاملHydrogen, Positronium, and Quarkonium
Most students of physics beyond the very lowest levels are familiar with the spectrum of Hydrogen, however, to approach even slightly differt system seems an insuperable task. However, in truth, the spectrum of species as diverse as Positronium and Charmonium bear a striking resemblence to that of Hydrogen, at least at low energies. The aim of this paper is to showcase the similarites and diffe...
متن کاملProtonium Formation in Antiproton–Hydrogen Collisions
We present a computation of the cross section of protonium formation in antiproton-hydrogen collisions using the nonlocal resonance model. It is based on restoration of the Born-Oppenheimer approximation, when the adiabatic electronic basis is replaced with the so called diabatic one. This allows us to separate the electron and hadron parts of our problem at the cost of a nonlocal potential in ...
متن کاملNegative ion formation in potassiumâ•finitromethane collisions
Ion-pair formation in gaseous nitromethane (CH3NO2) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO2 , O , CH3NO2 ,...

Ion-pair formation in gaseous nitromethane (CH(3)NO(2)) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO(2)(-), O(-)...
