摘要：

It has been recently suggested that there exists a neutral bound state of two neutrons and a A hyperon, (3)(A) n. We point out that by using either simple separable potentials or a full-fledged calculation with realistic baryon-baryon interactions derived from the constituent quark cluster model it can be seen that there is no possibility for the existence of such a A nn bound state. For this purpose, we performed a full Faddeev calculation of the A nn system in the ( I, J(P)) = ( 1,1/ 2(+)) channel using the interactions derived from the constituent quark cluster model which describes well the two-body NN and NY data and the Anp hypertriton.
