Nuclear-Charge Screening in Positronium Formation from Helium Atoms
An analytical treatment of the electron screening effect within an active-electron model is given for positronium formation from helium atoms. A first-order distorted wave approximation with correct boundary conditions is applied to evaluate the transition amplitude. In the range of impact energy for which the introduced perturbative approach is valid, both the total and differential cross sect...

متن کاملExcited-state positronium formation from helium, argon, and xenon.
The cross sections for the formation of positronium in the 2P state in collisions of positrons with He, Ar, and Xe atoms have been determined by measuring coincidences between the remnant ion and the Lyman-alpha photon from positronium. The maximum fractional contributions of these to the total Ps formation cross sections increase from approximately 0.06+/-0.01 in He to 0.12+/-0.04 in Ar and 0....
متن کاملSelf-consistent database for atoms and molecules
The scheme of construction of modern databases ideologically no different from specialized directories of the last century. The main drawback of such repositories is the accumulation of all the measured values of a particular atom or molecule with a subjective assessment by a distinguished group of authors reliability of the obtained values. Nevertheless, there are various methods of comparativ...
متن کاملElectron 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...
