Abstract
Estimates of the van der Waals coefficient C6 were made for various Ps-atom systems. Results for H and He are effectively exact and reproduce earlier calcualtions. It was emphasized that the C6 parameters for the rare gases and alkali-metal atoms should also be reliable with an expected uncertainty of 1-2%.
