Abstract

We use a microscopic three-cluster model with the $\ensuremath{\alpha}+\ensuremath{\alpha}+n$ configuration to analyze with astrophysical interests the photodisintegration cross section of ${}^{9}\mathrm{Be}.$ The valence neutron in ${}^{9}\mathrm{Be}$ is treated in the molecular orbit model, including continuum states by the box discretization method. It is shown that good agreement is achieved with the recently measured $B(E1)$ transition probability from the ground state to the first ${1/2}^{+}$ state when the box size is enlarged, resulting in reasonable reproduction of the experimental data for the photodisintegration cross section. The Coulomb dissociation of ${}^{9}\mathrm{Be}$ is also discussed.
