| Popis: | To explore a possible indirect method for $^{8}\mathrm{Be}$ induced astrophysical reactions, the $^{9}\mathrm{Be}=(^{8}\mathrm{Be}+\mathit{n})$ cluster structure has been studied via the Trojan horse method. For the first time a $^{8}\mathrm{Be}$ nucleus having an ultrashort lifetime is studied by the Trojan horse method and a $^{9}\mathrm{Be}$ nucleus in the ground state is used for this purpose. The $^{9}\mathrm{Be}$ nucleus is assumed to have a ($^{8}\mathrm{Be}+\mathit{n}$) cluster structure and used as a Trojan horse nucleus. The $^{8}\mathrm{Be}$ nucleus acts as a participant, while the neutron is a spectator to the virtual $^{8}\mathrm{Be}+\mathit{d}\ensuremath{\rightarrow}\ensuremath{\alpha}+^{6}\mathrm{Li}$ reaction via the 3-body reaction $^{9}\mathrm{Be}+\mathit{d}\ensuremath{\rightarrow}\ensuremath{\alpha}+^{6}\mathrm{Li}\phantom{\rule{0.16em}{0ex}}+\phantom{\rule{0.16em}{0ex}}\mathit{n}$. The experimental neutron momentum distribution inside $^{9}\mathrm{Be}$ has been reconstructed. The agreement between the experimental momentum distribution and the theoretical one indicates that a ($^{8}\mathrm{Be}+\mathit{n}$) cluster structure inside $^{9}\mathrm{Be}$ is very likely. Therefore, the experimental study of $^{8}\mathrm{Be}$ induced reactions, for example, the measurement of the $^{8}\mathrm{Be}+\ensuremath{\alpha}\ensuremath{\rightarrow}^{12}\mathrm{C}$ reaction proceeding through the Hoyle state, is possible. |
