Résumé : The study of K+p reactions at an incident momentum of 4.97 GeV/c suggests that the wide enhancement in the (Kππ)+ mass spectrum may be split into several resonant states. In particular, examination of the K*(892)π decay mode indicates the existence of the states K*(1230), K*(1280) and K*(1320), in addition to the well known K*(1420). The K*(1230) and K*(1320) have the properties expected from 1+ states produced by 0+ exchange. © 1967.
