Abstract
Irradiation of rutile samples by electrons of sufficient energy (>2 ke V) results in a negative potential at the sample surface. The interpre tation of the dose dependence of this surface voltage with the aid of the measured secondary electron emission properties of rutile, results for a primary electron energy of approximate to 1500 eV in an electio n stimulated oxygen desorption cross section in the range of 4 x 10(-1 8) < sigma(esd) (cm(2)) < 4 x 10(-19).
