Abstract:
A description is given of an investigation of the lambda hyperon production in negative-K captures at rest on complex nuclei in a heavy liquid bubble chamber filled with CF3Br. Main emphasis was put on a study of the lambda production in negative-K interactions which are not associated with the emission of charged or neutral pions, i.e. possible examples of negative-K captures on more than one nucleon. The total rate of lambda emission from negative-K captures in CF3 was estimated to 60 plus or minus 3. Lower and upper limits for the percentage of lambda hyperons produced in negative-K interactions on more than one nucleon were determined to 22 plus or minus 4 and 40 plus or minus 3 respectively. It was found that lambda hyperons are rarely produced directly in negative-K captures on pair of protons. The results of an investigation on hypernuclei produced by negative-K captures in nuclear emulsions are also reported. The reliability of a kinematic analysis method to identify the hypernuclei was examined by applying it to various categories of production and decay stars.
