摘要：
The ratio of pi(+)pi(-)-atom production rate to free pi(+)pi(-) pairs is obtained with account of the strong interaction in final states in the frame of the perturbation theory. It is shown that this ratio is expressed via a squared ratio of the well-known Coulomb wave functions and thus can be calculated with a high accuracy, (C) 1999 Published by Elsevier Science B.V.
