B 34 (2001) L187-L194 | | Subject: | Atomic Physics; Atomic and Molecular Clusters; Chemical Physics | physics.atom-ph physics.atm-clus physics.chem-ph | | Abstract: | We present a convergent variational basis-set calculational scheme for elastic scattering of positronium atom by hydrogen atom in S wave. Highly correlated trial functions with appropriate symmetry are needed for achieving convergence. We report convergent results for scattering lengths in atomic units for both singlet ($=3.49pm 0.20$) and triplet ($=2.46pm 0.10$) states. | | Source: | arXiv, physics/0103036 | | Services: | Forum | Review | PDF | Favorites | |
