a point at which outputs can impact beyond a narrow discipline interest group.
In assessing feasibility, and influencing design to maximize the antihydrogen yields, theoretical studies
of collisions involving Ps is of a key importance. However, to date, a sufficiently detailed treatment
is only available for a few states. In the present work we exploit convergent close-coupling method
and the classical CTMC method in a broad range of principal and angular momentum quantum numbers. Convergent close-coupling
method is used for relatively low principal quantum number n, but as n grows, classical CTMC method becomes
more reliable.
