摘要:
New data on the energy behaviour of ($) over bar np interaction at very low energy and ($) over bar pp --> ($) over bar Lambda Lambda reaction just near threshold are considered. Experimental observations in both cases indicate the existence of narrow (Gamma similar to 1MeV) ($) over bar NN and ($) over bar Lambda Lambda states of quasi-nuclear nature.
