New data on the energy behaviour of ($) over bar np interaction at ver
y low energy and ($) over bar pp --> ($) over bar Lambda Lambda reacti
on just near threshold are considered. Experimental observations in bo
th cases indicate the existence of narrow (Gamma similar to 1MeV) ($)
over bar NN and ($) over bar Lambda Lambda states of quasi-nuclear nat
ure.
