This chapter presents low temperature damage rates in ytterbium, tungsten, yttrium, zinc, and zirconium, as a function of electron energy. It illustrates the variation of minimum displacement energy of the elements Ag-Zr arranged according to periodic system, and normalized low temperature damage rates in silver, copper, molybdenum, niobium, and vanadium for protons, for deuterons, for 3He and for 4He(α) as function of energy. Normalized low temperature damage rates in aluminum for 4He(α), normalized damage rates in gold for protons, for deuterons, for 3He, and for 4He(α), and normalized low temperature damage rates in iron for protons are illustrated as a function of energy. Illustrations also include number of defects produced per implanted D2
+ or 4He+ ion during irradiation of platinum, number of defects produced by (α)-implantation and self-ion irradition in copper, gold and silver, and damage rates of silver, aluminum, gold, cobalt, copper, iron, molybdenum, niobium, nickel, palladium, platinum, tantalum, titanium, vanadium, tungsten, and zirconium under low temperature neutron irradiation. Low temperature damage rates of aluminum, cadmium, cobalt, chromium, zinc, tungsten, tantalum, platinum, molybdenum and iron single crystals, and low temperature damage rates of copper, molybdenum and platinum single crystals and of polycrystals as function of electron energy are also illustrated. Finally, directional dependence of displacement energy of iron, molybdenum, zinc, cadmium and cobalt, derived from low temperature damage rates are shown.
