Given a C\*-dynamical system (A, G, :), we discuss conditions under which subalgebras of the multiplier algebra M(A) consisting of fixed points for : are Morita Rieffel equivalent to ideals in the crossed product of A by G. In case G is abelian we also develop a spectral theory, giving a necessary a
