Abstract
The problem of signature inversion is studied by using a model of particles coupled to a rotor. We have assumed an axially symmetric equilibrium deformation and taken into account the γ vibration around it. The calculated signature dependence is found inverted in agreement with the experimental data if we adopt a set of moments of inertia which favor the rotation around the shortest axis, but not if we employ the set of the irrotational-flow model.Keywords
