Radiative strength functions (RSFs) in {sup 93-98}Mo have been extracted using the ({sup 3}He,{alpha}{gamma}) and ({sup 3}He,{sup 3}He{sup '}{gamma}) reactions. The RSFs are U shaped as function of {gamma} energy with a minimum at around E{sub {gamma}}=3 MeV. The minimum values increase with neutron number because of the increase in the low-energy tail of the giant electric dipole resonance with nuclear deformation. The unexpected strong increase in strength below E{sub {gamma}}=3 MeV, here called soft pole, is established for all {sup 93-98}Mo isotopes. The soft pole is present at all initial excitation energies in the 5-8-MeV region.
