Abstract: 
The relation between the shape variables (beta, gamma) of the collective model and the (lambda, mu) labels which define the irreducible representations of the SU(3) shell model is extended to a coupled rotor picture where one rotor represents protons (pi) and the other one neutrons (nu). The joint distribution, (beta, gamma), emerges as the overlap of the initial distributions, (beta(pi), gamma(pi)) and (beta(nu), gamma(nu)), where three Euler angles define the relative orientation of proton and neutron subsystems. It is shown analytically that the rotor construction for triaxial and axially symmetric shapes corresponds to a (lambda(pi), mu(pi) = 0) x (lambda(nu), mu(nu)) --> (lambda, mu)(rho=1) coupling in the SU(3) model.
