Abstract

Radiative strength functions (RSFs) in ^93\ensuremath-98Mo have been extracted using the (³He,\ensuremathα\ensuremathγ) and (³He,³He^'\ensuremathγ) reactions. The RSFs are U shaped as function of \ensuremathγ energy with a minimum at around E_\ensuremathγ=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_\ensuremathγ=3 MeV, here called soft pole, is established for all ^93\ensuremath-98Mo isotopes. The soft pole is present at all initial excitation energies in the 5\ensuremath-8\text\ensuremath-MeV region.
