摘要：
The effect of the SIGMA-LAMBDA coupling on the bound SIGMA-hypernuclear states is investigated in the case of the SIGMA--hypernucleus produced in the (K-, phi+) reaction on a target nucleus with double closed shells. In both SIGMA and LAMBDA-channels, the nuclear core is represented by a system of nucleons. The calculation of the width and energy shift of the bound SIGMA-states, in which the analytical expression for the two-particle Green's function is applied, leads to the conclusion that the SIGMA-LAMBDA coupling increases the binding of these states.
