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 in_{A}H^{4} obtained from its two-body and three-body decay modes. Within statistical error, the binding energy values of Λ in_{A}H^{4} and_{A}H^{4} are also the same. From a sample of 2

The ratio of non-mesic to π^{−}-mesic decay of light hyperfragments
K N Chaudhari S N Ganguli N K Rao M S Swami A Gurtu M B Singh
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.

On the hypernuclei resonant states_{Λ}Li^{6},_{Λ}He^{5}* and_{Λ}Be^{9}*
N K Rao M S Swami A Gurtu M B Singh
An attempt has been made to detect narrow resonant states of_{Λ}He^{5}* (I = 2),_{Λ}Li^{6} and_{Λ}Be^{9}* (I = 1) from amongst a sample of 128 uniquely identified_{Λ}H^{4} and 195 uniquely identified_{Λ}He^{5} 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 of_{Λ}He^{5} resulting from the decay of_{Λ}Li^{6} and_{Λ}Be^{9}* respectively.

The spin dependence of an weak interaction in the decay of hypernuclei
N K Rao M S Swami A Gurtu M B Singh
From an analysis of 468 hypernuclei (HFs) with ranges > 120 μm, the non-mesic to π^{−}-mesic ratio (Q^{−}) for_{Λ}He and_{Λ}He^{5} HFs was found to be 1.37 ±0.17 and 1.58

Final state interactions in the decay of light hypernuclei
N K Rao M S Swami A Gurtu M B Singh
The excited states of Li^{4}, Li^{5} and Be^{8} have been investigated by studying the final state interactions in the π^{−}-mesic decays of_{Λ}He^{4},_{Λ}He^{5} and_{Λ}Li^{8} respectively. The experimental results indicate the existence of final states like Li^{5*} at 1·8 MeV and Be^{8*} at 0 and 2·9 MeV to be dominant in the decay of_{Λ}He^{5*} and_{Λ}Li^{8} respectively; the results on the decay of_{Λ}He^{4} suggest the presence of a Li^{4*} state at about 4 MeV to dominate.
