Is the tetraneutron a bound dineutron-dineutron molecule?

摘要

In light of a new experiment which claims a positive identification, we discuss the possible existence of the tetraneutron. We explore a model based on a dineutron-dineutron molecule. We show that this model is not able to explain the tetraneutron as a bound state, in agreement with other theoretical models already discussed in the literature. [References: 40]
