    "abstract": "Transition frequencies of two spherical gas bubbles interacting in an\nacoustic field are discussed theoretically. In the present study, transition\nfrequency is defined as the frequency of external sound for which the phase\ndifference between a bubble\u0027s pulsation and the external sound is $\\pi / 2$. It\nis shown by a linear theory that a bubble interacting with a neighboring bubble\nhas three (or fewer) transition frequencies but only two natural frequencies.\nThis result means that the bubble has a characteristic frequency besides the\nnatural frequencies.",
