The low‐frequency form function for plane‐wave scattering by a fluid‐loaded thin spherical shell is characterized by the highQmonopole or “bubble” resonance. As the shell thickness is increased, the monopole resonance is observed to shift to higher frequency and broaden (i.e., theQof the resonance decreases). With a further increase in thickness, highQresonances appear on top of the spectrum of the monopole resonance. These low‐frequency, highQresonances, first reported by Diercks and Hickling [J. Acoust. Soc. Am.41, 380–393 (1967)] have never been satisfactorily explained. In this paper we present the results of our investigation, based upon the linear theory of elasticity, of these highQresonances. The dependence of the resonances on frequency, and shell and fluid parameters are presented along with the elastic stresses and displacements in the shell. Dispersion curves are generated from numerical solutions and a physical explanation for the strong coupling to the fluid medium is obtained.
