Experimental values of damage rates have been obtained for titanium for electron irradiations in the energy range 0.30-0.50 MeV. A suitable preirradiation annealing treatment has been found, and a value of 19.2±1.0 eV is determined for the threshold energy of atomic displacement for titanium. Experimental damage rates are compared to theoretical calculations of the cross section for atomic displacements.
