文摘We investigate the properties of A^+c- and Ab-hypernuclei within the framework of the relativistic mean-field model (RMF). It is found that no A^+c bound states can exist if the A^+c potential well depth |UA^+c| in nuclear matter is less than 10 MeV. If |UA^+c|is less than 20 MeV, A^+c cannot bind to the heavier nuclei with atomic number larger than 100. We suggest it is preferable to search the A^+c-hypernuclei from medium-heavy nuclear systems in experiment. Very small spin-orbit splitting for the A^+c in hypernuclei is a/so observed, and for the Ab it is nearly zero.
