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 2π+ decay events of hyperfragments the branching ratio ofAH4 decaying byπ+ toπ− mode is found to be (1·5±1·0)%.
