• Anisotropic damage productions were examined in electron-irradiated molyb-denum by using high voltage electron microscope. Formation of defect clusterswas most enhanced for electron beams with the exact zone axis directions anddecreased with an increase in a deviation angle from the axes. Saturated densitiesof defect clusters rroduced bv the irradiation were used as a measure of damageproduction, since Iinegr relationship was found between electron flux and thesaturated density of defect clusters. From the comparison between the electronflux dependence and orientation dependence of defect cluster formation it wasconcluded that the enhancement of damage production is due to the locallyincreased electron flux at the atomic positions effective for atomic displacement.
