Let T = {T(t)}(t epsilon R) be a C-0-group on a complex Banach space X dominated by a weight function omega(t) = (1 + vertical bar t vertical bar)(alpha) (0 <= alpha < 1) and let A be its generator with domain D(A). Among other things, it is shown that if the operator A has compact local spectrum at x is an element of X, then x is an element of D(A) and there exist double sequences of real numbers and (t(n))(n epsilon Z) Such that
