Investigation of binding energies of hypernuclei

Öz

In high energy nuclear reactions one may observe the production of manifold hypernuclei as a result of the capture of hyperons by nuclear residues. We have investigated the statistical disintegration of such hyper nuclear systems and its connection to the binding energies of hyperons. In the calculations we use the statistical multifragmentation model (SMM) adopted for the formation of hypernuclei in the high energy nuclear multifragmentation reaction events. It was shown within this model that the mass distributions are quite different for the fragments with different strangeness contents.
