Abstract

The energy dependence of the cross section for reactions $K^{+} n \to K^{*} (890) p$ and $K^{-} p \to K^{*} (890) n$ is compared over a wide range of incident momenta and found to be identical. This excludes odd $C$ -parity exchanges in addition to the dominant $π$ exchange. The conventional absorption model does not reproduce the rapid decrease of $ρ_{00}$ as a function of the four-momentum transfer. The Reggeized $π - A_{2}$ model of Dass and Froggatt reproduces the $t$ dependence of $ρ_{00}$ and $Re ρ_{10}$ , but there is serious disagreement for $ρ_{1 - 1}$ which may indicate the need to include $A_{1}$ exchange. The asymmetry in the decay angular distribution is interpreted as $S - P$ wave interference.
