Abstract
Field evaporation of iron and niobium in neon and in hydrogen was examined between 20 K and 200 K with an FIM. From the temperature dependence of the evaporation field and the field dependence of the evaporation rate, the activation energy for the evaporation was estimated and the effect of hydrogen was discussed.
