This process can be used at a linear collider to measure the selectron masses and the gaugino mass parameter M_1 very precisely.4 pages, 4 figures, Talk given at the 9th International Conference on Supersymmetry and Unification of Fundamental Interactions, Dubna, June 11-17 2001High Energy Physics - Phenomenologytext
