Abstract
The paper is a continuation of [1] and contains the evaluation of the (exact) LBB constant, in terms of the wave number, for typical problem s (all with spherical geometry) in elastic scattering. Solutions to th e problem of scattering of a plane wave on an elastic spherical shell, for different wave numbers, illustrate the dramatic effect of the mag nitude of the LBB constant on the convergence.
