Yield curves and photoneutron multiplicities have been measured for the isotopes /sup 176,178,180/Hf in a betatron bremsstrahlung beam in the energy range 8--21 MeV with a 0.125-MeV step. The measurements were made on-line with a computer. The cross sections were calculated from the yield curves by the Penfold-Leiss method with a 1.0-MeV step. The multiplicity curves were used to separate the contributions of (..gamma..,n) and (..gamma..,2n) reactions. Integrated cross sections calculated from the photoabsorption cross sections are given, and also average energies and deformation parameters. The results are compared with calculations using various versions of the model of coupling of dipole and quadrupole vibrations.
