摘要
Using local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the nn system, and the latest updates of the nΛ and ΛΛ Nijmegen ESC08c potentials, we study the possible existence of a ^4 ΛΛn bound state. Our results indicate that the ^4 ΛΛn is unbound, being just above threshold.We discuss the role played by the -1S0 nn repulsive term of the Yukawa-type Malfliet-Tjon interaction.
