The total photodisintegration cross sections of three-body nuclei are
calculated with semirealistic NN potentials below pion threshold, Full
final state interaction with Coulomb force is taken into account via
the Lorentz integral transform method. The experimental total cross se
ctions are well described and the sum rule sigma(-1)(H-3) agrees with
elastic electron scattering data. The calculated He-3 polarizability i
s 0.15 fm(3). (C) 1997 Published by Elsevier Science B.V.
