Abstract
In terms of the participant-spectator model for high-energy heavy-ion collisions, the probability that a hyperon is created from the participants directly in the nuclear single-particle states of the spectator fragment is evaluated. It is found that the magnitude of the cross section for producing a hypernucleus depends on both the lifetime of the hyperon source and the impact parameter of the reaction.
