Recent experimental measurements of charge transfer in ion collisions with circular-state Rydberg atoms (for which [ital m]=[ital l]=[ital n][minus]1) can be qualitatively reproduced using an elementary atomic model consisting of a classical electron in a circular orbit with an arbitrary axis of rotation defined by experiment. Contributions to capture are further separated into one-swap and three-swap charge transfers, revealing the relative importance of a Thomaslike mechanism for charge transfer at ion velocities of 1.00, 1.65, and 2.00 times the velocity of the target electron. The model is extended to estimate charge-transfer cross sections for ions incident on elliptic-state Rydberg atoms of specific eccentricity.
