The production of hypernucleus in high-energy nuclear collisions is st
udied for four different mechanisms; (1) coalescence of a spectator nu
clear fragment and Lambda particles from a participant part, (2) coale
scence of Lambda particles and nucleons both produced in the participa
nt part, (3) the secondary process by pi and K mesons, and (4) convers
ion of a Xi(-) hypernucleus into single- and double-Lambda hypernucleu
s.
