Résumé : New binding energy values for the hypernuclei 10ΛBe and 14ΛC have been determined while those of 13ΛC and 15ΛN have been reassessed. The existence of a narrow particle-unstable state of 12gLC is affirmed but the previously quoted evidence for the existence of a narrow state of the 14ΛN hypernucleus is shown to be invalid. © 1974.
