    • Abstract


      An attempt has been made to detect narrow resonant states ofΛHe5* (I = 2),ΛLi6 andΛBe9* (I = 1) from amongst a sample of 128 uniquely identifiedΛH4 and 195 uniquely identifiedΛHe5 hypernuclei produced by stopping Krmesons in a nuclear emulsion stack. From the experimental data presented, it is concluded that the production of any of these resonant states is not appreciable; upper limits of 20% and 15% are set for the proportion ofΛHe5 resulting from the decay ofΛLi6 andΛBe9* respectively.
