Similarity between positronium-atom and electron-atom scattering.

چکیده
We employ the impulse approximation for a description of positronium-atom scattering. Our analysis and calculations of Ps-Kr and Ps-Ar collisions provide a theoretical explanation of the similarity between the cross sections for positronium scattering and electron scattering for a range of atomic and molecular targets observed by S. J. Brawley et al. [Science 330, 789 (2010)].

Electron exchange model potential: Application to positronium-helium scattering
The neutral Ps beam provides a great deal of advantage over charged projectiles as a probe to study the structure of atoms, molecules and surface. Recently, there have been a great deal of interest in positronium(Ps-) atom scattering due to the improvement of Ps sources and Ps beams. Total scattering cross section of ortho Ps, which has a larger lifetime than para Ps, have been measured for var...
متن کاملLow-energy Scattering of Positronium by Atoms
The survey reports theoretical studies involving positronium (Ps) atom scattering. Investigations carried out in last few decades have been briefly reviewed in this article. A brief description of close-coupling approximation (CCA), the firstBorn approximation (FBA) and the Born-Oppenheimer approximation (BOA) for Ps-Atom systems are made. The CCA codes of Ray et a1 [I-61 are reinvestigated usi...

In the present work, the transition matrix elements as well as differential and total scattering cross-sections for positronium formation in Positron-Hydrogen atom collision and hydrogen formation in Positronium-Hydrogen ion collision, through the charge transfer channel by Two-Centre Close-Coupling method up to a first order approximation have been calculated. The charge transfer collision is ...
متن کاملVariational calculation of positronium-helium-atom scattering length
We present a variational basis-set calculational scheme for elastic scattering of positronium atom by helium atom in S wave and apply it to the calculation of the scattering length. Highly correlated trial functions with appropriate symmetry are used in this calculation. We report numerical result for the scattering length in atomic unit: (1.0 ± 0.1)a0. This corresponds to a zero-energy elastic...
متن کاملElastic positronium-atom scattering using the stochastic variational method.
The stochastic variational method is used in conjunction with stabilization ideas to compute the low energy phase shifts and scattering lengths for positronium-atom scattering. Results are obtained for the Ps-H, Ps- Li+, Ps-He, and Ps-Ps systems. The Ps-H scattering lengths are probably accurate to better than 5% and are the most accurate so far computed. The results for Ps- Li+ and Ps-Ps scatt...
