KS0*and its uses

We point out that Primakoff conversion of $K_L^0$'s produces $K_S^{0^{*}}$'s. This makes possible a practical tagged $K_S^0$ beam. In addition one can test the recent suggestion that $I=1\mathrm{}$ exchange effects necessitate large corrections to Primakoff measurements of vector-meson electromagnetic widths. It will also be possible to measure $\Gamma (K^{0^{*}}\to K^0\gamma )$ in a manner independent of the alleged corrections.
