Abstract
The resonance scattering of plane sound waves from a circular cylindrical thin elastic shell with a vacuum inside is investigated. The R-matrix method for suppression of the background contribution in the total form-function and for extraction of the spectral information (positions and widths of the spectral lines) is used. The resonance characteristics of the multipole order m=2 are analyzed in detail. The singularities which permit to distinguish the numerical resonance parameters for sound scattering from cylindrical and spherical elastic shells are discussed.
