It is known that in a certain case, the secondary Bjerknes force, which is aradiation force acting between pulsating bubbles, changes, e.g., fromattraction to repulsion as the bubbles approach each other. In this paper, atheoretical discussion of this phenomenon for two spherical bubbles isdescribed. The present theory based on analysis of the transition frequenciesof interacting bubbles [M. Ida, Phys. Lett. A 297, 210 (2002)] provides aninterpretation, different from previous ones (e.g., by Doinikov and Zavtrak[Phys. Fluids 7, 1923 (1995)]), of the phenomenon. It is shown, for example,that the reversal that occurs when one bubble is smaller and another is largerthan a resonance size is due to the second-highest transition frequency of thesmaller bubble, which cannot be obtained using traditional natural-frequencyanalysis.Comment: 7 pages, 7 figures, Revtex4; Comments added and typo corrected;  Accepted for publicatio
