A strong enhancement of the photon strength function at low {gamma}-ray energies was recently reported for several Mo isotopes. To study this enhancement further we have measured the spectra of two-step {gamma} cascades following thermal neutron capture in {sup 95}Mo. These spectra were compared with simulations of the {gamma} decay of {sup 96}Mo performed with the aid of the dicebox algorithm. Simulations with a large number of model combinations of photon strength functions for E1,M1, and E2 radiation are not consistent with the strong enhancement observed in the {sup 96}Mo({sup 3}He,{sup 3}He{sup '}{gamma}){sup 96}Mo and {sup 97}Mo({sup 3}He,{alpha}{gamma}){sup 96}Mo reactions. Predictions based on a combination of E1,M1, and E2 photon strength functions with no enhancement of the photon strength functions at low {gamma}-ray energies are in good agreement with the two-step {gamma} cascade data.
