We use a microscopic three-cluster model with the α + α + n configuration to analyze with astrophysical interests the photodisintegration cross section of 9Be. the valence neutron in 9Be 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 the 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 dissocitaion of 9Be is also discussed.
