Linear AAD interaction and the relativistic rotator

It is shown that the weak-potential limit allows us to reveal quite naturally the presence of the relativistic rotator in linear AAD interaction. In the language of extended constraint dynamics it is able to give all required rotator generators including the evolution equation of the Hamilton-Jacobi type suitable for rigorous quantization.Dedicated to Academician Václav Votruba on the occasion of his eightieth birthday.
