| Abstract: | We study the production ofΛ hyperons inp+A reactions on the basis of a BUU transport approach for32 S,65 Cu,120 Sn,197 Au,208 Pb and238 U from 1.1 to 1.7 GeV beam energy and evaluate the properties of the hypernuclei produced with respect to excitation energy, transverse and longitudinal momentum, angular momentum and mass. Furthermore, the decay of the hypernuclei by particle emission in competition with fission channels is followed by a statistical model calculation. We find the systemp+197 Au at about 1.5 GeV to be optimally suited for the production of heavy hypernuclei, where theΛ-decay is expected to be dominated by nonmesonic decay channels. |
