    "abstract": "It is known that in a certain case, the secondary Bjerknes force, which is a\nradiation force acting between pulsating bubbles, changes, e.g., from\nattraction to repulsion as the bubbles approach each other. In this paper, a\ntheoretical discussion of this phenomenon for two spherical bubbles is\ndescribed. The present theory based on analysis of the transition frequencies\nof interacting bubbles [M. Ida, Phys. Lett. A 297, 210 (2002)] provides an\ninterpretation, different from previous ones (e.g., by Doinikov and Zavtrak\n[Phys. Fluids 7, 1923 (1995)]), of the phenomenon. It is shown, for example,\nthat the reversal that occurs when one bubble is smaller and another is larger\nthan a resonance size is due to the second-highest transition frequency of the\nsmaller bubble, which cannot be obtained using traditional natural-frequency\nanalysis.",
