Nonmesonic Decay of Hydrogen Hyperfragments

Abstract

Approximately 35 000 K~-capture stars in an emulsion stack were examined for hyperfragments. Using a mass selection criterion for all events, a sample of 13 7r~-mesonic decays and one nonmesonic decay of hydrogen hyperfragments was identified for the purpose of estimating the relative rates of decay for the 7r~-mesonic and nonmesonic modes.
