The structure of bound and resonance states of the hypernucleus7ΛLi is studied within a three-cluster model. This nucleus is considered a three-cluster structure consisting of4 He, a deuteron, and a lambda hyperon. The chosen three-cluster configuration allows us to describe more accurately the structure of hypernucleus7ΛLi and the dynamics of different processes that involve interactions of lightest nuclei and hypernuclei. The main goal of the present investigations is to find resonance states in the three-cluster continuum of7ΛLi and determine their nature. A set of narrow resonance states is detected at the energy range 0 < E ≤ 2 MeV above the three-cluster threshold4 He + d + Λ.
