Cross section for atomic displacement by fast electron, (calculated by the McKinley-Feshbach formula)

Table 1
Threshold energy (Ed), threshold acceleration voltage (Ud), and cross section (s) for atomic displacement of pure element by fast electron irradiation [1, 2]. Most of the values for Ed and Ud were taken from the references [3-5]. A list of the systematic experimental data was firstly summarized by K. Urban [3,4] and slightly modified by H. Fujita [5]. The s values were calculated using the McKinley-Feshbach formula, which is frequently used in radiation damage analysis [6-9]., (Updated on 02/21/2014)
