Description
In the study of three-body weakly-bound systems, a three-body interaction is always introduced to take care of the dynamics that cannot be accounted for by two-body interactions. In order to get some insight into these dynamics, in this presentation, we study the relevance of the three-body interaction as the number of neutrons in the three-body system increases, considering $^6{\rm He}$ systems.
It is found that by removing this interaction from the structure of the system, the ground-state binding energy of the $^6{\rm He}$ system drops by about 80%. This shows that the three-body interaction plays a significant role in the dynamics of a three-body weakly-bound neutron-rich system.
