Résumé : The three-body final states of K+p at 3.5 GeV/c show large fractions of quasi-two-body processes, by abundant production of K*(892) and N *(1236). The K*(1400) is also observed in constructive interference with the N *(1236). The production and decay angular distributions of K*(892) are compared to the predictions of the peripheral models and to the results at 3 and 5 GeV/c. In partieular, the agreement with the peripheral model with absorption, satisfactory at lower energy, tends to deteriorate as the energy increases. © 1967 Società Italiana di Fisica.
