Photodisintegration of Be-9 through the 1/2(+) state near neutron threshold and cluster dipole resonance below giant dipole resonance was measured with quasi-monochromatic gamma-ray beams produced in the inverse Compton scattering of laser photons. The cross section for the 1/2(+) state is revisited, being consistent with the 2001 data. The cross section for the cluster dipole resonance is consistent with the cluster dipole sum-rule which however degenerates for the two-body (n-Be-8) and three-body(n-alpha-alpha) configurations.
