Abstract: A necessary and sufficient condition is proved that a set of points $\{ {r_n}{e^{i\theta n}}\}$ in the unit disk be the set of zeros of an analytic function with infinitely differentiable boundary values for every choice of $\{ {r_n}\} ,\;0 < {r_n} < 1\;{\text {and}}\;\sum {(1 - {r_n}) < \infty }$
