Binding energy values of hyperfragments from a sample of 541 uniquely identified mesic decays with mass numbers A=3 to 14 are presented. There does not seem to be any detectable difference in the binding energy value of Λ inAH4 obtained from its two-body and three-body decay modes. Within statistical error, the binding energy values of Λ inAH4 andAH4 are also the same. From a sample of 2

A new method of obtaining the charge spectrum of light hyperfragments from their residual range distribution is described. This method has been used to determine the ratio (Q−) of non-mesic to π−-mesic decay of light hyperfragments. The values of Q− for hyperfragments of different charges are found to be in good agreement with theoretical calculations of Dalitz.

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.

From an analysis of 468 hypernuclei (HFs) with ranges > 120 μm, the non-mesic to π−-mesic ratio (Q−) forΛHe andΛHe5 HFs was found to be 1.37 ±0.17 and 1.58

The excited states of Li4, Li5 and Be8 have been investigated by studying the final state interactions in the π−-mesic decays ofΛHe4,ΛHe5 andΛLi8 respectively. The experimental results indicate the existence of final states like Li5* at 1·8 MeV and Be8* at 0 and 2·9 MeV to be dominant in the decay ofΛHe5* andΛLi8 respectively; the results on the decay ofΛHe4 suggest the presence of a Li4* state at about 4 MeV to dominate.
