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 کاملPhotodetachment cross sections of the positronium negative ion
The cross sections for the photodetachment from a weakly bound positronium negative ion Ps− below the threshold for the formation of Ps(n = 4) are calculated using the hyperspherical close-coupling method, and are compared with the corresponding spectra for the H− ion. Detailed resonance structures in the spectra near the Ps(n = 2, 3 and 4) thresholds are reported for the first time. The off-re...
متن کاملObservation of a shape resonance of the positronium negative ion.
When an electron binds to its anti-matter counterpart, the positron, it forms the exotic atom positronium (Ps). Ps can further bind to another electron to form the positronium negative ion, Ps(-) (e(-)e(+)e(-)). Since its constituents are solely point-like particles with the same mass, this system provides an excellent testing ground for the three-body problem in quantum mechanics. While theore...
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 کاملGas Flow Influence on Negative Hydrogen Ion Generation within the Microwave-driven Negative Ion Source*
H ion was generated through two processes within a volume Csfree source. The density of molecule hydrogen gas will impact on the electron temperature within the primary discharge chamber that will influence the population of vibrational excited H2. Within the extraction region, the interaction between molecule hydrogen and H ion will is cause the dissociation of negative ion. To better understa...
