To explore a possible indirect method for 8Be induced astrophysical reactions, the 9Be=(8Be+n) cluster structure has been studied via the Trojan horse method. For the first time a 8Be nucleus having an ultrashort lifetime is studied by the Trojan horse method and a 9Be nucleus in the ground state is used for this purpose. The 9Be nucleus is assumed to have a (8Be+n) cluster structure and used as a Trojan horse nucleus. The 8Be nucleus acts as a participant, while the neutron is a spectator to the virtual 8Be+d\ensuremath→\ensuremathα+6Li reaction via the 3-body reaction 9Be+d\ensuremath→\ensuremathα+6Li\phantom\rule0.16em0ex+\phantom\rule0.16em0exn. The experimental neutron momentum distribution inside 9Be has been reconstructed. The agreement between the experimental momentum distribution and the theoretical one indicates that a (8Be+n) cluster structure inside 9Be is very likely. Therefore, the experimental study of 8Be induced reactions, for example, the measurement of the 8Be+\ensuremathα\ensuremath→12C reaction proceeding through the Hoyle state, is possible.
