| dc.description.abstract | 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: [Formula Presented] This corresponds to a zero-energy elastic cross section of [Formula Presented] © 2001 The American Physical Society. | en |
