Résumé : The decay branching ratios of K*0 (1420) into K+π-, K0π+π- and K*+(892) π- are measured in the charge exchange reaction K+d → K*0 (1420) ppS using data from a K+d bubble chamber experiment at 4.6 GeV/c incident momentum. For the branching ratio (K*(1420) → K*(892)π)/(K*(1420) → Kπ) a value of (0.54 ± 0.16) is obtained. The results are compared with previous measurements. © 1974.
