Abstract
The collective-coordinate method for the quasizero modes is suggested. Quasizero mode means that a direction in functional space exists where the action varies slowly. As in the case of exact zero modes the corresponding integration is nongaussian and should be performed exactly. The method is illustrated by calculating the instanton-anti-instanton interaction in double-well quantum mechanics.
